I am so sorry for your loss- there are not words.
I'm a psychologist (Psy.D) in the states, and I just wanted to mention (I think a pp did as well) that a psycholgist with either a Psy.D or a Ph.D can diagnose bipolar (or any other mental illness) and also be involved in the (non-medicinal) treatment aspects, like therapy.
As terrifying as it is, PLEASE do whatever it takes to get some medical or mental health professional involved. Go to the emergency room-- ask your husband or a friend to give you a "dealline" of finding a doctor and then take you to one or start making calls for you. NONE of this is your fault, and you deserve treatment and to feel better. Please take care of yourself and surround yourself with others who can help.
