That's too bad you have to go when you don't particularly want to. Will your own pdoc be there? Is she a different one from the previous hospitalization? Maybe this hospitalization will go differently since she knows your concerns?

I could see trying to straighten out your meds (that don't appear to be working) with you in the hospital rather than at home. Thinks can get/seem much worse but eventually get better.

I would write out your concerns or print out this post and give it to your pdoc and parents and anyone else you trust and maybe they can make your hospitalization more comfortable for you.
