sorry you didn't get a reply before now......
do you have a therapist? if not, please try to make an appointment with one so you can bounce your feelings off of someone IRL. and continue to post here. i'll watch for you.....
it sounds to me as if your husband has more problems than you. would he go for couples therapy? if not, go for yourself. you can ONLY fix yourself....he'll change if he's ready to and he has to make that decision.
being bipolar is not the end of the world, even though it can feel like it sometimes. i'm major depressive, so i'm always on the floor..trying to scrape myself up..but good days do some and things do get better.....just hang in there, talk to your doc and get a therapist.......please keep me updated......xoxoxo pat
