Idk if this helps or if you also have ADD but I just read this before deleting for ideas in general:

It doesn't give a lot of suggestions but it did say it is the reason things can seem nice then - not great in retrospect? (Doubt, shame, self-loathing etc). Surprised me that was the reason. I think perhaps it's possible subconsciously or consciously if it feels not great, so why repeat it> Until of course (we) realize it's not an accurate looking back. So persevere and challenge those thoughts/ feelings. I guess assume all is 'weller' than it 'feels'.
Hope that makes sense, I can't find the words today. Hope you feel better and more like your self soon. Hugs to you.
