To whoever reposts this: I know how it feels to have a friend leave you for someone else. In my case they left our whole group for another group where I didn't fit in. the worst part about it, was the fact that no one in my group was fazed by it. If they had been, I would have been able to distract myself by comforting them. And it is better that no one reacted as I did. not only do I hate seeing my friends sad, but I also acted stupidly. I hope whoever is going through this can get through it without too much pain.
