i suffer a lot from depression and was on disability after 15 years of not working. I think you are ahead of the game by being in the hands of a good therapist. I don't think we can fight bipolar but instead I am beginning to believe we have to work with it. i really start drowning in depression when i fight with it and feel hopeless. when i try to work around it, i do much better.
if you go on disability you won't be isolated. it sounds as if you have a thoughtful husband. you also won't have the stress of not performing at your job...both are biggies...i think you have to be bipolar who suffers the pain of the depression to understand....it is so frustrating to not be understood.
