Bipolar is a weird thing! My sister and I both had long stretches with no symptoms. Ten year periods during the time we were raising our kids. I wasn't on meds during that time and only just got on meds in the last couple of years when my episodes started getting closer together.
During that time I didn't think about being bipolar much. I'm grateful my kids had one sane parent for much of their childhood.
Anyway, enjoy your stability!! Yay!!
