Sorry to hear about all this. Sounds like a really difficult spiral to get out of, and not having that support from family sucks. But hey, at least you have strangers on the internet right? I'm not going to repeat anything that anyone else has already said, or likely will say, but when I had speech therapy the only thing that helped me was when my therapist told me to tell people that you have a stutter. So: "Hi, my name is <name>, it's nice to meet you. Before we start the interview I just wanted to let you know that I do have a stutter, so if I stutter during this interview it's not down to nerves, and it doesn't prevent me from doing my job effectively" Then keep going. I'm not going to lie, I've never tried it as I'm stubborn af. But the idea is comforting to me. And rejection sucks. But is rejection worse than stagnation?
