Thank you for giving us some back ground. I have not looked up your meds so am not sure what they are that you have listed on your signature line.
It does sound like your mother may be bipolar....
there is a book called shadow syndromes that you may like. ramsey writes it I believe. It talks about mental health issues as a spectrum.
You are under a great amount of stress. Please be careful with yourself.
exercise, make that a priority. Eat well and sleep. I hope the baby issue is on hold for a while.
