Thanks everyone for responding. It means a lot to me to have people take time out of their lives to help me out.
I completely agree with everyone that I can't be of much help to my family if I'm not mentally well myself, but I can never focus on myself without being overwhelmed with worry. I think that's the biggest reason I can't seem to help myself. Even if I take time out for me all I'm thinking of is if my family is okay: whether or not they're hurting themselves or if someone else is hurting them. I'm just a constant worrier.
Anyways, thanks again everyone
