That is a very vicious cycle that I have been caught in several times, I agree with the others, do something just for you it can be as simple as reading a favorite book or taking a hot bath, anything that relaxes you.
Are you in therapy? Have you looked into local support groups? Many locations have support groups for mothers and/or people dealing with depression. I personally found therapy and group therapy helpful in dealing with these kind of issues, I used to have a real hard time making friends because I just couldn't shut up.
