Try to talk to your school/uni counselor. They might not be able to treat your condition, but at least they can help in arranging something, at the very least referring you to a doctor.

Good idea. Physical problem can mess with your head too!
I remember reading one book written by a psychiatrist, he got one crazy experience: accidentally treated a patient with orange juice.
Turns out the patient has low blood sugar, high enough not to pengsan but low enough to mess with the brain. Glucose drip 1 day & go back home sane again...

Got other causes also, thyroid problem is quite common, chronic infection also....

So go get yourself checked!
