There are many good comments on this thread, so I hope that you consider them carefully. One point I'd like to add is this. Try to find small things that you can start and finish in a reasonable amount of time. Maybe something you can do in an hour, as against, starting yet another task that will take days or weeks to finish. In my experience, actually finishing tasks that have some value to me give me a little hit of dopamine or some other brain chemical, and that often improves my mood. I wish you the best.
