IMOPO, you need to get way out of your head for a few hours or even a day or two.

Forget about therapy, all the work you are doing, and fully engage (as best you can) on something else.

Your brain will continue to work on the problems you've outlined, plus you get to have a little break (dare I say fun!) and you can come back with fresh eyes.

I believe it was Einstein that said "you can't solve a problem with the same mind that created it".

I say, go out, try and find a newer fresher mind. therapy will always be there.
