I am so sorry you are feeling this way. I, too, suffer from low self-esteem and low self-confidence to the point I have even had other people tell me I am my own worst enemy. I don't know how long you have been married but think of this: those other girls were exes, your husband chose you. There must have been something wonderful and special about you, being he chose you. Is there something going on in your relationship right now making you feel this way? Does his family mistreat you? I have a wonderful husband but my in-laws can be real good at making me feel inferior. As I have gotten older I have learned not to pay them any attention, but they can still be annoying. God bless and I hope you feel better soon. I send you hugs.
