You need to see your current pdoc immediately & advise of the anger outbursts and anxiety. Current pdoc can deal with this--you don't have to wait for new pdoc, you need to improve working relationship with the one you have. Slow down, deep breath, describe as calmly as you can how you feel, how bad it is, what help you need.
Don't panic with pdoc. Tell pdoc you will work with him/her--but you must be a team and you must make progress. These drugs are not the best possible for you ... and that is the only acceptable goal.
Call tomorrow. Go sit in the waiting room. Remain calm & quiet, but make it clear that you need a professional helping you now.
