Unfortunately some meds do have pretty bad side effects. But you need to weigh what the worst option is: living in so much distress as you are presently or trying something new? (ie. something new which might possibly help you)

I am sorry your parents view being sick as being weak or not trying hard enough. With all due respect, your parents are wrong. Being human means being fallible. I am afraid this is a message many parents 'teach' their kids but it doesn't make them right.

If things are really bad, it might be worth considering new avenues. I wish you well.
