I am not sure about it being a MLC, but it sounds like she has been through a lot of disappointments in her life and may feel a little bit like a failure. It also sounds like her body has gone through a lot also and she is most likely very sub-conscious about it. Continue with what you are doing. Give her her space, be supportive, be her friend and like always be patient. You are doing great.
