Hey, Please consult a physician & check if there could have been any physical damage in her stomach or thigh. Coming to antidepressant, there has to be a reason why she was put on it in first place..?? Was it because of her reaction to situations..?? Those negative thoughts & dip in the mood might still exist though sugar level is in control hence allowing her to sleep only when she is on antidepressants. Have you considered counseling..?? If you haven't, please do and see if that can help her manage life better.
