I used to be on medications for that sort of thing, coincidentally, it make everything worse, I freaked out far more on the medications.
Nowadays, I rarely freak out, if the medications aren't working for you, wean yourself off of them and try more natural ways to relax, I recommend sleeping to relaxation tapes and keeping binders of things you like with you ((weather they be pictures/information on your interests, perhaps a scrap of a fabric you like the feel of, simple things.))
