((BNLsMOM)) Can you go for a walk with your kids every day? Being outside in the sunshine is technically a treatment for minor depression in and of itself. Also it would give you a little exercise. Perhaps being with your kids would give you the motivation.

As for the meds, it sounds like it's time to start all over. Fortunately (and unfortunately) there are hundreds of medications used to treat bipolar disorder. I'd discuss the vicious cycle you've been going through and see if you can put your heads together and come up with a way to break it. Medication and lifestyle changes maybe? Like adding something you like to do once a week (yoga, an art class etc.) so that you don't completely isolate.
