How do you usually deal with it?

Find someone hotter and rub it in their face. Watch them SEETHE

Hook up with strangers

Plan my ex's death. The murder scenes and potential cover-ups that went through my mind.

I give myself a day to watch movies/tvs in the dark and mope around then I channel my emotions into something productive ( Working out, writing, working, etc etc)

I do this

Then i do this

I always tell their secrets and some lies.
After that I need lot's of Vodka & Tequila.

The last breakup I went through, I just listened to music and took a long hot shower and just kind of thought about everything; what went wrong, the good times, how everything would change now, etc. It helped that I waited until a few hours after it happened to tell my parents and then my dad and I drove around and he just kind of talked to me about it and it helps. It really helps to vent to someone you love about it. And it also helped that I went out with my friends and just enjoyed having them because I know they can't leave me the way my ex did; they'll always be there for me, and spending time with the people that truly love you and going out and trying to have fun and forget about your ex is honestly the best thing to do. Even if it doesn't instantly work, it's better than sitting around moping about how miserable you'll be without him or her, or how angry you are. Moving on and spending time with the people that won't leave you will make you feel better, though. I can assure you of that.

Be depressed for months and obsess over their every social media move, then eventually meet someone else and forget about their dusty asses.

You start by calming down and being thankful for the good that you guys once had.
