I agree that finding humor and letting time pass by are important to healing, and part of both of those things is learning how to laugh at myself and not take myself so seriously. Maybe then, each mistake I make or have made won't seem to define me so much...
As far as making things right with the people I've wronged, I just wonder if that isn't a selfish desire. I don't want to force people to forgive me, or make them relive something that may have been confusing or painful for them as well. Yet, I can't shake the feeling that we're only ever as good as our last goodbyes (i.e. leaving things broken, hurt, or unclear keeps the relationship/friendship in this perpetual state of being broken, hurt and unclear).
Paynful, how do I forgive myself? Conceptually, I can read what you wrote and agree with your advice, but I can't seem to put it into practice. It's created this strange time loop where I find myself in the same mental place that I was weeks, months, and even years ago. I'm reminded of the song 'Keep Breathing'; "The storm is coming, but I don't mind. People are dying, I close my blinds. All that I know is I'm breathing. I want to change the world... instead, I sleep. I want to believe in more than you and me. But all I can do is keep breathing."
