Obsessed with decluttering, donating, trashing, getting rid of objects.

I have been through therapy multiple times for anxiety and obsessiveness, but this has just gotten ridiculous. I have an urge to get rid of items like books, old toys, old electronics, extra blankets, clothing, etc. I used to only occasionally destroy things to get rid of them, but now needing to get rid of things has caused me so much anxiety I don't know what to do. This started around 2020-2021, after I had multiple mental breakdowns due to stress from schoolwork and living alone. Once I was back home, I thought I needed to get rid of things to feel better. Most of my old toys and some of my clothing I donated. When my parents said we donated enough, I was livid, and began to cut up my clothing I didn't want just so I could have fewer articles of clothing.

I have gone through my grandparents' possessions and attempted to clean up their office space, which made them both furious. I went through my parents' belongings, shredded book covers, and destroyed jewelry, they were beyond disappointed in me. When I can't donate things, I cut them up, destroy them, and throw them away. I sneak things into the recycling if they can be recycled, just to get rid of items. I need to get rid of items or else I am constantly thinking about how to get rid of these items. Once I am done with a certain section of items, like toys or clothing, I move on to another type of item, like decorations, CDs, DVDs, etc.

Part of me doesn't want to stop decluttering, but at the same time my parents have threatened multiple times to kick me out over my decluttering obsession. I will say my parents have been very kind to me over the years, no abuse, etc. whatsoever.

It's ridiculous. Part of me knows I need help because this is affecting my relationship with my family, but at the same time I love getting rid of things because it helps me free up space.

I don't know what to do. I need advice. Please help.
