My brother is so calm cool collected ..he has 3 boys all 1 year apart , teenagers now

But he just rolls with the punches doesn't get up or down works loads of overtime but finds time for family.
We both grew up in the same home same parents same rules same everything .. I am the Bp'er that can cry as the drop of a hat or go manic and internalize everything and self harm .. Hard to imagine such polar opposites .
I hear ya
