You might want to try saying the Word "No" to yourself whenever you start to feel guilty for not having done something self effacing, or when you start to feel the feeling inside that you "should" do something above and beyond for someone. It's important to sort out when you really WANT to do it and when you think you SHOULD. I admire you for seing that your family really needs you to be stronger, but you also need to do thins for yourself, dear! HUGGS and good luck!
