Hello sir. Good luck. In addition to all the other good advice, if there is someone you know and respect, and who has a stable living situation overall, I would strongly encourage reaching out to them and ask for help and meeting with them regularly, both for the advice that they can give, with their more intimate knowledge of you than those of us online, and for the encouragement and motivation that comes from feeling like you have someone in your corner. It's one day at a time.
