I've never heard such a thing as a mental health office dropping a family becouse one person is seriously ill. Aren't they going to get your new meds a change to help before covering their collective asses?
Please don't do anything rash I think they are over reacting to past records and you might make a case for letting this new approach work and the fact you have been taking a AP, that is huge.
I don't know what state you're in but some now have outpatient commitment options instead of being baker acted to a facility they can order you to outpatient which mean complying to take meds as RXed and keeping apointments....in other words doing what you've been doing in the past few weeks and it still covers their ***. You might ask about this as an alternative. Legally they are supposed to use the least restrictive choices first.
