Hello, Louisa91, and welcome to Psych Central! I am so sorry you have to deal with the ignorance and abuse of your parents on top of everything else. I honestly don't know what to suggest for changing their minds.

What does your therapist say about the situation? If you don't have one, then see if you can get one to talk to.

It also sounds like you need to tell your psychiatrist as soon as possible what the med is doing to you. There are many, many other meds available. I also suggest you tell him about how you feel about the hospital experience--and ask that if you go, then he see about med changes/adjustments while you are there and allow you to talk to the social worker/therapist who would be available. (At least a social worker has been available at all the hospitals I have been in.) Maybe some other professional could try to intervene on your behalf, too.

You'd think your sister with a degree in psychology would know about mental illnesses and take your side. I guess she doesn't want to make your parents mad?

Aren't there other online schools that might offer your degree?

I hope I have helped some. Maybe somebody else will have some suggestions. I sure hope things will get better for you soon.
