How do I break this vicious cycle?

I feel a little depressed, my mother is a bad hoarder which bothers me to the point that I developed an eating disorder and skin picking disorder. I know the only way for me to save myself is to move out. I never hurt my body by picking on my skin or stress eating 🥺😭 when I'm away from home, but I'm here now and I happen to be often. The problem is I can't get out of here now because I just picked on my skin and I can't control my eating disorder. I already gained some weight and my skin looks bad, it makes me feel so insecure ashamed. I can't go on a walk, I didn't even open the door for the delivery guy yesterday. It's hard for me to take care of myself since I already look bad. I'm embarrassed but sometimes I don't brush my teeth, wash my hair etc because I feel like I'm not worth of (self) care, love (my way of thinking is "everything or nothing"). When I look at my house and how cluttered, dirty it is, I feel so frustrated that I can't change it and I feel dirty myself so I quit trying to take care of myself. It's a vicious cycle. But when I'm away from home, I glow, I do sports, eat healthy because I enjoy doing that and I'm so happy.
Please help me break this cycle.
