Hope you are feeling better today. Not bipolar but experienced extreme sadness with the loss of my 11 year old daughter. they symptoms were sort of how you described. but you know all you can do is take it one day at a time. Of course with bipolar you also have to take your meds and try to not get too stressed out about things. use your coping techniques and whatever else you pull strength from. you gotta have an anchor. for me it is prayer. I pray when I am down. It is soothing to believe in a higher power, for me it is. also being in nature helps. if you have a back porch, maybe spending time out there on the patio with a good book or listening to your favorite music, anything you enjoy to lift your spirits.
It's funny how you envy those who stay home. I am just the opposite. with these rheumatoid hands and fingers that look like curly fries, I envy those who work outside the home and can actually be good at it and not have to apologize for an illness. that's why I am going back to school, to learn to do something I can do whether i am physically abled or not.
Hang in there. as the old folks say, trouble don't last always. there will be good days coming around in no time.
