This is truly horrible. I must say, your writing sounds pretty composed for someone who has just gone through a life-changing event; you must be a strong person who can hold it together, even in the face of hardships. I think what you need to do now is prioritize and then live one day at a time. Mental health court is priority number 1. Disability is priority number 2. You had a great job; you must be eligible for good state disability insurance (not federal, which is hard to get and does not pay much money, but state, which is easier to get but pays decently for a short period of time). If state disability declined you (I am surprised that it did, with Bipolar I, last episode manic, criminal history within mania, etc.etc.), appeal. Give them more medical evidence. If you get the state disability, you do not have to worry about homelessness in the immediate future. Do not take calls from anyone you do not know - let everything else go to voice mail. This way you won't be bothered by shouting collections agents. FINDING OUT about visitation is priority number 3. Not visiting, but just finding out. For that, you need a social worker / case worker. Ask your therapist where to get one.

Where do you get psychiatric care and free/small copayment meds? Because you are indigent, you must be eligible for subsidized care.
