You have seen a therapist. Do you ever get work with any coping strategies. Are able to do any of them?

Distractions can help like games-it helps me focus and relax.

I use the tired out phrase "this too, shall pass". And try to get out of the depression quicksand.

I like goal setting, even though it's taking me forever to do some of those tasks.

I let go of my negative thoughts as much as possible(even though they seem to stick to like glue to paper, it's difficult slow action).

In the worst times, I repeat the Serenity Prayer silently to myself many times till I fall asleep.("God grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference." Or for short "let go, and let your higher power take over."

I don't know if any of that helps, but I hope you can find acceptance and peace.
