Oh trust I so know the feeling! I have four kids, going to be five to deal with soon. Plus trying to work and go to school at same time.... It is so not easy by any means!!! But if you really think about it, what keeps you even going, when you just wan to quit? If you can think of why you haven't quit, then you just need to keep reminding yourself you are stronger than you realize you are and that you have made it this far, you can go farther!
