Anecdata: I am homeless. I will not go to a shelter. I have a compromised immune system. I am on the street to get well. I have goals. Etc. I do my best to avoid most other homeless people. They are typically unclean, unhealthy, have super poor boundaries and think I should want a hug merely because I am also homeless...etc..ad nauseum.
I run a small website where I am trying to put together ideas on how the homeless can solve their own problems. I am not looking for a handout. I think one of my biggest problems is the Othering of the label I have. But I had that problem long before I had this particular label. Anyway, I think on that a lot and learning to "behave normally" after a lifetime of never managing that looks to me like one of the big things I most need.
