Anxious About College Roommates

Hey all, this is a long one. So I'm off to college in a few months and I'm really freaking out about the whole roommate situation. I can't handle the idea of living with a stranger especially with my anxiety. I use my room as a safe space to be alone and to decompress. being social is a chore for me and I relish the time I can get away from society. Sometimes locking myself in my room is the only thing keeping me from having a panic attack. I like to talk to myself a lot and I get really upset if my sleep is disrupted. I just don't know how I'll function if I don't have that safe space where I can let my guard down anymore and it's freaking me out. I'm trying to get my therapist to sign a form request accommodations for mental illness but I'm worried it won't be accepted. there's 2 girls (twins) I'm friends with who are going to the same college and I'm considering asking them to room in a triple with me but part of my anxiety disorder is the feeling that everyone secretly hates me and I'm scared they're gonna say no. We’re only school friends and don't really hang out outside of that but at least I am familiar with them and our parents are friendly. I don't know if they would be remotely interested at all or if it would even lessen my anxiety. I'm completely at a loss here and spiraling. I know I probably sound crazy, but that's what this app is for right? I'm really hoping some of you understand what I'm going through because everyone else I've talked to doesn't get it. Thank you to whoever takes the time to read all of this and any advice is greatly appreciated.
