Yeah, I have to pretend I'm a totally other person. Make a phone call? Fill out important paperwork? Get up for work in the morning? How would someone that does that all the time (and doesn't hate it) do it? Try to temporarily be that person to get started, then regular you gets to be you again after you start. It's like acting I guess, and works pretty well.

This would probably work, but you shouldn't have to run away from your own space because the other person might show up. I think it'll create a lot of anxiety about being in the dorm.
