One more thing i wanted to say, I've never been in this situation as deep as you but i would say keep taking care of yourself physically and mentally. Do pushups, situps, squats, pull-ups at the park, if you are healthy enough. Keep bathing, brushing your teeth, washing your clothes, looking and smelling as good as you can. not on some "I can't let other people see I'm down" shyt. Just on some personal pride shyt. Keep your head high. You might be down right now but you're not "lesser-than". You still deserve to reasonably take care of yourself as much as you can.
Also try to keep a healthy level of social interaction with people. It will help to keep you sharp and might expose you to opportunities. Maybe try to see online places that offer services, see if you can volunteer, see if you can offer skills in exchange of compensation, see if they can offer shelter in exchange of work...
I know you didn't really ask for advice but i figured I would still say it in case someone else reading it needs to hear it
