How do I fix my sickly problem?

I have been taking whiffs of paint thinner like at least twice everyday, which its a very strong smell and contains petroleum distillates. I only do it bc someone poisoned me with something just like it. and I get nausea from it everytime even just when I think about it. my parents don't know but they know I have been doing crazy things and they want to get me evaluated for problems. and I feel im fine if I got away from the school that I got poisoned at and found away to stop whiffing the smell I'd be better. I don't know how to stop though. help?
