Top Ten Most Terrifying Mental Illnesses

The Top Ten


Literally Psych meds must be key at all times to deal with people like this. Once there off it the mental mind games get really tedious and fustrating.

Schizophrenic people aren't dangerous. Horror movies have portrayed us in such a negative light, society now thinks of “psycho” killers using chainsaws and wearing masks. Schizophrenic folks are so much more likely to harm themselves than anyone else.
(Source: I have schizophrenia.)

Even as someone who doesn't have schizophrenia, reading about experiences that people with the disorder have endured are extremely scary, like as if you're having a nightmare whilst awake.

I have this. It's horrible to live with. But I feel like I can't take medicine to get rid of my delusions. They're mean, but I have to do what they say.

Multiple Personality Disorder

I have to live with it and I have no control over my life!
This disorder is also known as "Dissociative Identity Disorder" occurs often when you are traumatized.
Yes it's real!

Otherwise known as dissociative identity disorder. It truly sounds awful. And so difficult to explain to new people.

We are incredibly lucky to live in a time when these illnesses (and even run-of-the-mill depression and anxiety) are given the respect they deserve--most people understand that you can't just "suck it up."

Wendigo Psychosis

I seen this before, it wasn't so bad until I saw these birds circling around someone. Geez they were like waiting.

I was at school this one time and I started ripping my skin off. I said I wanted to eat myself. then my friends ran away

Bipolar Disorder

This one is terrible

Your not bipolar because you have small mood swings.your weather is not bipolar. When your in a very bad deppresive state it's the worst and manic is can feel good at times but its hard can't slow down no matter how much people tell you to and you can't sleep and everyone and everything iratates you.and thean you crash in to a dark deppresion.and the parnoia and halusinations are so scary.


I've kind of gotten used to being depressed. I don't know if I'll ever be how I was before. And in a way, I don't want to.

Same here actually, I don't even know if going back to normal is possible at this point for me.

Borderline Personality Disorder

I have this, and it's awful. I am genuinely scared for myself and others and my emotions can be so strong that there is no way to let them out

It's terrifying. You feel like a constant danger to yourself and others, always leaving emotional and mental pain in your wake. One day you may love someone, the next wish them out of your life, and then beg to return from fear of abandonment.

Hitler had this disorder and the disorder led him to kill Jews in Gas Chambers this disorder is terrible and dangerous

Alice in Wonderland Syndrome

Worse than schizophrenia.

Anxiety Disorder

This is by far one of the most terrifying mental illnesses. I have had it almost my whole life and it’s made doing simple things, such as talking to others, a living hell for me. I am constantly afraid of failing tests, being bullied, dying, etc. Sometimes, I am staying up all night crying and shaking so hard that I can’t breathe. Anxiety is no joke. No one deserves to go through it

I am surprised that this wasn't already on the list before I added it. It is literally a disorder about being terrified.

I can’t believe it is so low on the list. Not only do people have to live with this type of stuff but they have almost no control over it. I am a 15 year old with this problem and I am scared to do anything because I think people would always judge me and when I talke for my dad about this he said to “suck it up, you are probably over exaggerating” and from then on I didn’t know what to do and thought everyone was a scared as I am.

Alien Hand Syndrome

O my god think that your hand hand betrays your brain

Obsessive Compulsive Disorder

As a sufferer of this, I know it's awful. I'm not a NEAT FREAK, but sometimes my mind forces me to stop what I'm doing and go do something over and over again until I'm satisfied. When I go to sleep at night, I turn the light off once, and even though I know nothing's there, I keep turning the light on and off until I'm satisfied. I don't like when people misinterpret OCD and perfectionism. I hate when people in school just say "OCD!" when they/or someone else is a neat freak. That's not what OCD means. My parents don't believe that I have this, but I do. I'm in NO WAY super neat, yet my brain makes me do things over and over again until I'm satisfied. If you don't do it, you'll be restless and uneasy. It's like a routine that you have to do even if you don't want to do it. Except, if you don't do it, you'll be anxious and won't sleep at night. Example: I was sleeping one night and got up at 1:00 a because my mind was troubling me over not zipping my backpack. So after hours of ...more

I suffer from OCD and it’s a living nightmare. I have literally zero control over my thoughts. And in most cases the worst possible thought appears in my head. I also have a terrible obsession with numbers. I won’t do anything in 2s, 5s, 6s, or 8s. I don’t know how the numbers came up but each one is associated with a different disastrous event that my brain thinks will occur if I do anything in these numbers. I also have a tendency to knock on wood if literally anything unsettling comes into my mind. For example, if I see one of those smoking commercials with the people with holes in their neck I will knock on wood because my brain thinks I will get one if I don’t. I’ve done a great job hiding but yet again I am not a very social person so no one has gotten close enough to really no about it.

Oh Yeah. I have that.

The Contenders

Kluver-Bucy Syndrome
Cotard Delusion

This is also known as walking corpse syndrome... Here is some insight. Anyone with this believes they are a dead corpse, walking like a zombie. They think they died and are rotting away. This can cause people to die of starvation or dehydration. They usually root into this by having depression and suicidal thoughts.

Capgras Delusion

Capgras syndrome is an uncommon type of delusional disorder. It is characterized by intense, unwavering feelings that a close friend or family member has been replaced by an identical impostor. A sufferer recognizes the face and behavior of the loved one, but is convinced that he or she is a double.

this must be extremely awful...


Imagine living in constant fear of dying from illness or injury, but this isn't just ordinary everyday fear that people can put to one side and ignore. This is continual. It is terrifying. You notice a small bodily symptom and your mind inflates it until it's stage 5 deadly cancer and you're about to die. But you're too scared to go to the doctor in case they confirm your fears, because you'd rather not know either way than have it confirmed for you. Hypochondria should at least be in the top 10.

Wow. I do that all the time. 'oh no I have a headache. That means I'm about to have an aneurysm and die!' that's me constantly

Post Traumatic Stress Disorder

This causes adults to take sexual interest in prepubescent children and fantasize about sex with them. Thankfully, there are treatments and therapy that can help keep it under control and make them less likely to molest children. Not all child molesters are pedophiles, and not all pedophiles are child molesters. As long as he/she doesn't act on their fantasies, they are not a child molester. So far, there is no cure for this horrible disorder.


yup got this

Stockholm Syndrome
Panic Disorder

Panic attacks (especially multiple attacks a day) are the worst. A panic attack feels almost exactly like a heart attack. The sweating, tingling in arms, heavy feeling in my chest, nausea. Also hyperventilating until my vision becomes almost black. It's horrible.

Panic attacks are absolutely terrifying.

You feel things in a way others can't emagine.but you sure do suffer for it.


I have a good friend that had this. He wasn't munching on anything too dangerous, but it was still... Bizarre.


Of course this isn’t as bad as depression, schizophrenia and borderline personality disorder, but it still causes me to have sensory overloads and stressful moments regularly which are still draining and annoying. I can call it Asperger’s disorder as well because that’s why I have. I really can’t take the stress anymore these days and it wish it would go away. With that I mean I wanna get the stress away, not the autism because that’s something I have been born with and that’s just how I am. I wanna live without stress before it’s getting too late

This is the last comment I make by the way until I’m coming back in September
