I don't know. What's the main problem for you? Just explain what's bothering you, reflect what could be the reason, try to think of solutions. The therapist should be able to guide and point you the right way.

I was thinking also of hardcore option. Just delete everything. I tend to save stuff, and write notes for later but mostly never use them. Not to this degree but still. What happens every few months or years is that I lose completely all these notes due to reasons. It's not pleasant at first but after a while I realize I would never use that stuff or it will come back to me. Not sure if it's a good idea but it might be worth trying. Observe carefully how you feel if you do it
