My mother raised four kids on her own, one of them was a troubled child who often was in trouble with the law.
(It wasnt me btw : p)
She worked 40 hours a week while raising us alone, and even managed to graduate from college while doing it. I know shed say it wasnt in any way easy : p But I can say that I really appreciated all that she did for us, how thankful and grateful I am for what she did for us, and how she is an inspiriation for me to try harder. I even often think about her when I work, and how I want to do as well as she did, no joke : p
I cant offer you much support, as Im not in your situation at all : p But speaking as the child of a single mother, I have huge respect for her, and am really happy that we had a mother who was loving enough to work as hard as she did for us.
