If the info about bd members isn’t on the website w the hotline number, google that. My brother has headed a number of boards. If you get a strongly worded letter ready you will be ready to send it once you find an address, and are less likely to let this go. We all get busy.
So sorry you are having such a rough period. Hope you have touched base with a therapist and a meds doctor? Hugs!
Laurie really knows about these things. She has participated at high levels in community mental health organizations.
