'mylifeneedshelp' I have a few ideas for you, these are pretty basic.

First is try to get some exercise, even if its inside your house, but better yet take a walk around the block, at night and no-one is around, if its hard for you.

Break down everything you need to do into smaller jobs. With that application, fill out just a line for now.

Plan everything in advance, say fill in a line of your application at 11am, another line at 12pm, another at 1pm, you get the picture. As you complete one job, the following become easier and easier, you just need to take that first step, and follow it with a second, like learning to walk again.

I do think you are depressed, look around this site, particularly this page for some potential self-help, using cognitive behavior therapy, since you can't afford a doctor, you can try things to improve even if it only helps a little.
