Blue, I think you have to say more or something different to get their attention.
I know you are concerned about being forced into IP.

I think that is a chance wel all take when needing emergent help.
Yet, if you feel it can be handled with the right meds and safely at home, then ... maybe contact the pdoc and tell his voicemail or something that you are experiencing a severe episode and you think, if it is handled well and right away, you can get a h andle on it.
You cannot secure meds to help right now, without you pdoc. You've got to get through to him. Same with your therapist. You need to tell them something that WILL get their attention. I know this feels very risky for you,.
Hang in there....
