My husband is bi-polar. I have lived with him unmedicated (he was mis-diagnosed).
I'd take a knee walking alcoholic any day of the week over an un-medicated bi-polar. At least with an alcoholic you kind of know what to expect - not so much with the other.
If he is I hope he will get the treatment he needs. When it is treated it is very manageable.
As for you run, run as fast as you can.
