I am really sorry you feel like this. I used to have a very negative voice that played in my head saying mean things to me. I think a combination of what people have said to me in the past and depression making me feel more worthless. I did not experience any sort of severe abuse, though. I think having positive mentors and relationships in recent years, plus a therapist who had a kind view of me slowly chipped away at that negative voice, but it still crops up sometimes.
Is anything making you feel like this more recently? Is there a reason you feel you need to put your husband's needs above yours, instead of something a bit more equal? Your needs are important, too.
