First of all, stop pitying yourself like that. White black thinking won't help you, not only that, but it also comes forward as attention seeking behavior.
Now, as what you can do about is simply ask yourself why you would care about those people who are against you?
Your life doesn't resume how people perceive you. You need to find a purpose.
Also, I'd get those hallucinations checked if I were you. It is pretty much serious and may be a condition that causes those symptoms.
