Don’t over think! That’s how you get more upset. Try & do whatever you can to keep your mind off of it. The fact that you’re getting depressed over this makes me sad. You shouldn’t have friends who make you feel this way. True friends would include you when it comes to things like that. Maybe it’s time to break off from them & try to make new friends. I’m not saying just stop talking to them, but find new friends who make you feel like you’re apart of something.
