What about at your mother's? Would it be any better there?
And absolutely I'm with you, I wouldn't want to be where I had the feeling I wasn't wanted and they were just putting up with me.
Did you say in the past that you had an internship lined up? For when this is over?
And probably the best advice I could give you right now is to the best of your ability, stop thinking, stop your mind going around in ever more panicky circles, focus your energy on something more pleasant, and as Eckhart Tolle says, Align With What Is. Realize you can only deal with one thing at a time. Where you will live, #1. Where you will work, #2. And so forth.
