A pizza is a great idea. Don't be too hard on yourself. You could beat the crap out of yourself and lose a bunch of time on that and the past is still the same as it was. All you can do is make amends where you need to, learn from what happened and that is all we can do. Sometimes I am sad that I cannot go back and do it all different, but I think that is very typical of all people, not just us addicts. Have a slice and get to your meeting. I hope you can still make that meeting and be with some real life folks.
