I called 211 where I live. Phone hours start at 8AM, nationwide. You can access the crisis line anytime 24/7. Give them your zip code and they can find any and all resources to help you. Most states have free legal aid, and resources for many of the issues you face. They can help prioritize all you should do to protect yourself. Make a list before you call so that you can request all aspects of your situation.
Tell them everything you need.
1. Access to meds (if requires transportation)
2. Birth Certificate replace to regain control of your SS payments, State ID, etc.
3. Redirecting SS payments
4. Request rent abatement due to circumstances, or assistance contacting Landlord. Who's name is on the lease as responsible party?
Door lock issue? One legal, and two how to pay for. Can landlord help with that?
5. Banking
6. Mail
7. Legal re bank and abandonment. Don't like the email contact with him. Get an intermediary.
@Fadeaway Birth Certificate replacement. Is that already being processed? That can also be done on line. Perhaps someone here you trust could help that with a payment for the processing. (not sure if third party could be involved, if just for payment I think they should be able to keep the process private to you) PM Sammyiam. I would help, but am broke my self.
"Wait times for birth certificate applications are approximately ten days to a couple of weeks, depending upon how the application was received: in person, via mail, or online. Online processing with debit or credit cards generally speeds up the process."
**!! Other concern I have is your mail situation. Does he have access to your mail? Do a redirect with the Post Office first thing, or is a postal box, remove joint access, or request lock change, or a new box just for you. Even a neighbor might help, church group. Sounds like you have transportation issues. Ask 211 about help with that.
With a little help from your friends.
