I feel useless

I went to great college, met nice people, but I won't be able to return. I don't have a way of paying and I don't know anyone to cosign. My mom and I don't have a relationship. I apply to an online school buy don't anyone to put on my reference on MNP. I'm living with my mom but feel like I'm always talked down. I try to be nice because I need her to sign my fafsa. I can get a job to save my life. I'm not go in anything. I can't talk to people and it messing me up and being alone in my room is killing me. I don't know what I should do.
