Well... it's been a few days since you posted this. I hope you're doing at least a bit better. You wrote you were feeling angry & wondered how to move on with your day. Perhaps you figured that out for yourself?
I struggle with a lot of anger too. And, in my case, what I do is to simply strive to accept what I am feeling with mindfulness & compassion & then forge ahead with doing whatever else needs to be done. I, at least, find that as time goes by my anger tends to subside. This doesn't always work though. When it doesn't something such as going for a long walk is the best I can do.
