I'll just say it, from someone who is similarly in your boat:

if you're even questioning it, there's probably something there

think about someone who is questioning their sexuality. there has to be some reason they're doing it.

i agree that there are probably varying degrees, like everything, but comeon...you're obviously very aware of the stigma. bipolar people who are highly functioning exist, and your doctors' metric is probably quality of life. if you can hold it together, it's not really life-affecting. it's just the way you are.

you could probably say you are bipolar-ish but have developed systems on your own for dealing with it.
