😞it’s a lot but not a book

I been sleeping a lot and it’s not cus I’m pregnant cus I’m not, but it’s because I’m so depressed. I’m always crying, I always got anxiety because everything goes wrong for me and I bite my lip and inside my cheeks so much because of it and now it looks like I get beat up because it’s always like that. I’m losing a lot of weight, I don’t eat and if I do I eat once every few days or a few 50cent bags of chips once a day. I’m up all night as sleep all day. What should I do to get out of this depression? Not for me but for my son😞
