I'm not really sure how I can help you but just from personal experience when a situation arises that gets me stressed out and I can't handle it I just sit down, close my ears and ignore what is going around me for a second while i take a deep and slow breath. I get through the situation the best that I can knowing that its ok that I am not perfect and after it is all said and done with I'll find a nice quiet place outside that I can rest and relax (if its warm) or I will go and just chill out by a windowsill looking at the street and thinking about what happened at my own pace so that I can learn from what happened.

I'm not sure if that helps at all but it works for me.
