What is wrong with my mom?

oh my god you have had it rough and it sounds as though you dont really need advice you just need to vent your anger and frustration, you also seem very sensible and well balanced, i think the reason your mum is on facebook so much is because on there she doesnt have to be herself, she can be who she likes, any age and background, just about anyone, she doesnt have to be a person with problems or illnesses, in her mind she can be a lovely young woman whos fit an healthy and happy, with wonderful children and a wondeful life and all the while hiding the real her, this is also why she wont take medication, in her eyes she sees it as a failure, a weakness, from what you have told me your mum has been able pretty much to do as she pleases, well now she cant, shes ill and she hates it and anything that reminds her of it, i dont know why shes like she is with her children, having a son in the army whos been to afghan 3 times i know i always keep in touch with his girlfriends, and as long as all of you bothers and sisters stay in touch theres not much more you can ask for, be well.
