Help me please peoples!?

alright so first of all i want to say im sorry:( also what your going through im going through the same thing at school i got my teeth knocked out by some girl in my class a few months back and now whenever i say anything bad about someone they bring that incident up. also my friend also rejected me coming to his party and it made me feel some type of way but all i do is take a deep breath and think if they didn't invite me to their party then their not true friends to begin with. i feel what your going through and i hope this helped.
