I don't mention my regrets because they were traumatic, and at my expense, some humiliating even.
I may be a lot of things, but I'm no masochist, I also know the road to hell is paved with good intentions and I have caused misery and suffering by being helpful and concerned with the well being of the people I've loved despite my good intentions behind my choices. Sometimes you just have to buck up and carry that cross because you can't know the outcome until all the consequences have come home to roost. That's what it is to be an advanced primate from Earth.
