I also have no regrets about ANYTHING (my parents, past, ANYTHING) because I make believe there is no "past" (53 years), there is only a "present". At least you have a child and are most likely younger (you can have MORE "present" that is meaningful, count your blessings).
It's strange to say, but life now seems to have a "larger" meaning for us (whatever that means).
At least we survived (I would wish I didn't, but in order to do that, I would need a "past"),..Living beyond life.
