I really believe what happened is less important than how one reacts to what happened.
There's really no excuse for being stuck in a situation and complain or brood, we were never truly stuck in anything either.
We. can. do. literally. anything.
With no one to stop us but ourselves and our mental constructs. Lets use that ability to do good as you said!
My friend, agreed 100% with you. But then it is easier said than done. We must have that mindset to be able to move forward despite great challenges and difficulties.
Of course. Good things are always hard to do. And respect for you to be able to do so even in the face of such adversity at the time.
