I have said this to other people, have you read Dr. Burns "Feeling good". There is a wonderful section on these types of thoughts and how to shut them down. Also, I am married with 2 kids and I feel unloveable sometimes but then I remind myself that is a completely false statement and all in my head. It is my past talking, my parents, my teachers, whoever put that thought in my head to begin with, it was their junk and I don't have to feel that way. I am not saying it is easy, feeling that way when you are overwhelmed is kinda normal, but in everyday life you have to think positively. I have learned alot in the last year, mainly in therapy and going to church, spiritual growth has helped me in this area. I go to a great Church called Solomon's Porch in South Mpls, if you are in the area sometime give it a try.
