No matter how poorly something went. No matter how unlucky you got on so many things.... you're now alive and here... you made it this far.... so stop trying to change the past and figure out 'what now' because the future even though it seems so hard to change is much easier to affect than the past.

I want to caveat that because one can change the past.
