How do I stop this habit? I'm scared for my health?

I had someone poison me with paint cleaner and I turned out ok but now I take a paint thinner and take big whiffs of it and the smell is well like paint thinner which is kinda like a gas smell. I whiff it more than once a day and it upsets my stomach and my eyes water and I get hot and kinda a headache. i don't know what will happen if I continue but I also don't know how to stop. please help me
