Decluttering and Emotional Attachment to Stuff

I really want to declutter and simplify my stuff and life, but I am emotionally attached to a lot of things. I also know I have trouble releasing things because they still have use or value. Finally, I think a big part of my challenge is confusion in my own identity, who I want to be, releasing who I was, scarcity thinking, and fear. Any tips? Any resources here in SCS I missed? Thanks!
