Can i be wrongly prescribed psychiatric medicine? how to get out of this trap? i've been through too many and fear i will never be the same again.

Too little info: Without knowing what kinds of problems you're having and what medications you've taken, it's impossible to answer your question specifically. Broadly, not everyone even with severe psychiatric problems needs medications--and those who do don't always benefit. If you're feeling trapped, consider getting a second opinion, maybe from a psychologist, about the nature of your problem.

Psych meds: Depends on how you define wrong?. You say you have been thru many psych mds, granted they all cannot be right but all cannot be wrong either. You can get more opinions if you like but sounds like you are struggling with insight issues.
