We are going to have break-through episodes even when our meds are working for us. It's frustrating to lose our balance. That said, we don't have to eat humble pie just because it appears we are dependent on meds and the health care system to keep us on keel.
If you're not already, try to keep a daily record of how you feel during the day - angry, happy, silly, and what you were doing at the time of your anger, what set you off. Then take this into your team and read it to them/express yourself standing up. That might get their attention. Sometimes we forget the details or down play our feelings while we sink into the chair.
Good Luck!
