How do you pull yourself away from a emotional situation?

Excuse yourself will be a way. Sometimes its also good to deal with the emotions in your time then to always run from it.

The best way to look at a situation objectively is to take a step back and breathe. If you can, give yourself 24 hours to react to an emotional situation/decision. Odds are that your first reaction won't be your best unless you give it some time, whether it's anger or passion or sadness with another person or event. It's best to give yourself 24 hours and then you can approach a situation/person with less emotional investment and a clear head.

Whenever you have the emotions pop-up, just go and do something you like, to get your mind off of it. For example, you can listen to music, you can draw, you can talk to your friends, you can try a new makeup look, go to the mall, anything you like. That will drive your attention away from it. Sometimes if you have flashbacks, what you can do is wear a rubber band on your wrist and just snap it really hard over and over again until those thoughts leave, because when you're snapping, your brain's focus will automatically drive to what's happening on your hand.

Think about something positive. Or try to see the good in it. Look on the bright side. Try doing something that makes you happy and stop you from thinking about what caused you to become emotional

I walk away and say that I wouldn't like to talk about this around others or I say that I need a little air. You can remove yourself from this situation by letting others know you need a minute.

Depending on how emotional the situation was, my coping methods usually range from separating myself to spending time with friends (girl's night) eating ice cream and junk food, listening to music or just dancing to lift up my spirits. Talking it out as well with someone I trust is another.
