Honey, I know how you feel, believe me. I fight this feeling, too. You have to find a way to keep on keeping on. You were a nurse, right? Maybe you can do some part-time work helping homeless people. That would really help you a lot, knowing you are helping people less capable than yourself. I am doing it part-time by doing misc. work for a homeless shelter online. That and making dinner for my husband every day is the only thing that makes me feel useful.
