That's pretty tough! If it's chemical based.... there may be no other option than for meds, to make it go away.. if its situational tho, it's likely that it can get better with out the meds.
Do you have any access to herbs or anything where you live?
EDIT: Is there a way to try and apply for internship in a different country through your school? usually the last few years are when they do that for people.
