Being low happens but take care of yourself so that you don't get locked up in a psych ward. Apply at your state/town's social services for heat / cash assistance and get food snaps to tide you over til you are back on your feet. Talk to your landlord maybe there is maintenance you can do in exchange for rent, and try selling stuff you no longer need. Get out of bed when you can. The bad shit has been going on for decades you can't fix asleep.
