Is bi-polar related to codependent?

How is bi-polar related to codependent?

Can a bi-polar person be considered a co-dependent?
Yes, a codependent person can be bi-polar. I believe they are related problems.
My theory is that the Super-responsible person who comes out of a Parental Inversion family system has suppression fo the Inner child which causes a life of depression. It also leads into all kind of ‘codependent’ type relationships.
The personality system that keeps the Inner Child bottled up sometimes breaks down and the Inner child breaks out and does stuff it has been prevented from doing. There are now no controls on the Inner Child and the result may feel pleasant but end up disastrous.
That is, I believe, how bi-polar gets set up.
