Sorry to hear IBZ, but ask yourself the question "what will I gain from being sad?"
One of the reasons that I felt sad after falling was because I wanted to change the past, I wanted to feel like a failure. That was all part of me wating to be in control, and being sad that I wasn't able to change the past.
One day at a time!! There is no reason that what happened yesterday has to make any difference in the decisions that I make today. Today I will make the right choices for today, no matter what happened yesterday or two minutes ago.
Just KOT brother!! You deserve to live now and get the most out of!!! (I mean it, you really deserve it, you are not a bad guy, you are a good guy who is learning how to deal with life!!)
A freilechin Yom Tov!!!!!
