I think I'm overreacting. I'm just a dumb angsty hormone fueled high school teen.
What's the reason for your overreaction?
Because I've been cheated on by someone who was dumb enough to date me in the first place
Do not put yourself down because of someone else's actions. If you are feeling down about it, get some support from friends and family. Being upset is fine, but don't blame yourself.
I'm going to make as violent comic about it and post it online for everyone to laugh at.
Making a comic can be a good outlet for your emotions. Don't make it so violent that people become concerned. But it is good to put your energy elsewhere.
