I'd suggest that you be at least as kind and gracious to yourself as the people you think you hurt have been to you. If you're human, being less than kind (read not perfect) at least once in a while just goes with the territory.

Everyone lives and learns. Or, maybe not everyone learns but apparently you have! So give yourself LOTS of credit for that. Don't allow your ego and human pride to stop you from laughing at your own imperfections, forgiving yourself for past mistakes and letting them go. Only then will you be ready to move forward.

ANd remember - angels can fly because they take themselves lightly!
