It's all the same over and over again

I'm in constant fight or flight mode everytime I think too much about going back home by myself. I don't want to live alone anymore and I can't seem to be able to find people to live with. I don't have family back home and the closest people I know might not be able to receive me at the moment so I'm in constant nervousness of what will happen to me when I get back. I can't stand the thought of being by myself and I am terrified about it. My anxiety is through the roof and I'm at the verge of just asking this family friends to please let me stay with them and that I'd do anything they might need just for me to stay with them. The idea of being alone terrifies me and the worst part is that it seems like I will have to be alone, there are no options and I hate it.
