I have not had surgery yet, but I can't tell you how many times I have heard this sort of problems from people who have lost weight, either from WLS or not. Its hard to explain but, overweight people know who they are, for example my friend was overweight she very quickly lost a bunch of weight, she no longer knows who she is or where she fits in, kind of an identity crisis, when she was fat, she was always "the fat girl in the group" once you get used to that for a long period of time it becomes ingraved in your head. Now she is struggling with her relationship, her job, her life in general. I dont know you, but maybe its something like this that you are experiensing.
