I've got to keep coming back to the gastric bypass. It's well documented that some people, after bypass surgery, develop other addictions, like sex addictions or compulsive gambling. And even without that, gastric bypass can result in any number of vitamin deficiencies, which can cause depression or other mental illness. Does she get B12 shots, take lots of vitamins, do the things she ought to do to keep her nutrition sound? Has she had any tests of her vitamin status lately?
Then again, she might just have a personality disorder of some type. But in the setting of gastric bypass surgery, I'd sure wonder about a physiologic cause.
