If the antidepressants are making things worse talk to(or have your parents talk to) your doctor about mood stabilizers instead. Ask your parents to look up and show the doctors and ER staff the dangers of antidepressants in children under 21.

I see you are in canada, I dont know much about how it works up there but dont understand why they refuse to have you evaluated at a children's psych unit, that part doesn't make sense. Ask your parents to call one of those psych hospitals and ask for help.
