Salvation Army - Sounds like a smart ass comment but they usually seem to be able to help , in any case they are a source of assistance in getting through the mazes.
Depression can be a real problem. You get a series of uncontrollable downers and you react to them. I had my Father-in-Law pass away, 4 months later I was laid off (job moved, I couldn't), 4 months later my Dad died on Palm Sunday, and I went to an interview where I knew the people, the system and was basically told that I had the job, went to my Mothers and there was a message waiting that they had been told not to fill the position and to lay one of their folks off, then we went to make funeral arrangements. and about 6 months later my Mother-in-Law passed away. I got to the point I wouldn't apply for jobs because if I didn't apply I couldn't get rejected. I didn't even work on projects around the house I now had the time to do (wife worked) because I was afraid I wouldn't get them finished. Downer on top of downer and withdrawal to avoid any more downers. Finally I had my annual physical, and the Doc said, it's depression, if anybody deserves it, you do after what you went through. Went over the symptoms, got me on some light meds. Decided not to go after one of the regular jobs (I had been consulting at $45 - $90/hr hellish commute for that one, not sure still if it was worth it) but one I really enjoyed at whatever pay.
That did it my attitude turned around. I started having a few small completions and then more and bigger. Let's just put it this way, my wife decided to remodel the kitchen and I did all but a little of the electrical. Obviously my inability to complete even little tasks was gone. so completing that was a real upper. Went out and got another job, so I now have twwo part-time jobs I enjoy, and a kitchen that needs only to have the ceiling finish sanded, the patching is done, final paint and upper cove molding. Waiting for Ma D to decide on lights.
So go out and get something to do, even if volunteering, get a few completions under your belt, even if they are small ones, once you get back to a positive pattern where even a few small things go right., you'll get an attitude improvement. You need to slow that spiral or stop it. Then you can get things moving up even if slowly.
Hang in there.
