What mental illness do i have?

No one here is qualified to make a diagnosis of a mental disorder based on someone's self assessment. That's not how it works.

you can't ask a bunch of strangers who aren't qualified in the mental field what illness you have and expect a right answer.

just alone on what you've said is vague, we don't know your medical history, how you were raised, etc. saying you want to kill someone doesn't make you a psychopath, saying you like to stare at people doesn't automatically make you autistic either.

go see a psychologist if you're genuinely concerned, and get a professional diagnosis instead of asking people on the internet to tell you what's wrong.

its called stop bein a fuckin pussy and git yalls shit together syndrome

Go talk to a counsellor, doctor, psychologist or psychiatrist. It isn't your fault, and it doesn't mean there's anything wrong with you, but the bullying sounds like it's definitely had a damaging effect on you.
Please don't take any steps to harm anyone or yourself, that will make your problems worse.
Get help, you'll be able to recover.

Is this a game show? What's the prize for answering correctly?

Seriously, only a professional can diagnose you.

Schizophrenia.

You need to suck more cock. Protein count is down.

Staring at someone when you're shy and introverted ? I couldn't do that!

As other people have said, you need to see a professional to be diagnosed with a mental illness.

All of them.

Staring OCD?
