TLDR at the bottom for those who can't make it through my (context providing) bitch fest.

Ok, I think I remember this as an ADHD thing, but I seriously have hoarder tendencies. Not like a dangerous level things aren't rotting or whatever, but I feel genuine emotional pain whenever I have to get rid of things.

For some things it makes sense. A prom dress I'm never going to fit into again (which also brings up body stuff but that's another subreddit) would be pretty emotional to get rid of.

But I feel it about EVERYTHING. Everything either has emotional sentiment or has a memory attached, even not particularly important ones are so hard.

I feel like the movie inside out, and they say ok, these are your memories, now you'll have to keep them organized (you're kidding right?) Or get rid of them. How can I be ok with that?

Because in theory yea, that little song book I accidentally stole from choir in middle school is useless to me. BUT then I remember how we practiced, the performances, the solo I had, and suddenly I have to keep it. It's like if I throw that thing away, the memory is gone forever because I won't remember to remember it.

I'm just so emotionally exhausted from all of this. I moved out of my parents house years ago, and while I "cleaned" the room, my sister will be moving into it for a few months and she doesn't want to live among my things.

My fiance is understanding of the issue, but he doesn't have the problem, so his suggestion for making it better is to throw all my stuff from my parents house away sight unseen, his logic being that I've lived without it this long so clearly it's not that bad. I panicked and told him on no uncertain terms that if he did that I would be returning my ring and he backed off immediately (he's a good guy, just very... utilitarian).

Ok how do I fix this what do I doooo???

TLDR: need to take all my shit from my parents house, not enough room at my place, getting rid of things hurts my heart even if it's "not important" any advice because there's only so many walls on which to build shelves that will fill up very very quickly.
