Sorry things are going rough for you.
I didn’t like 6th grade and wasn’t crazy about the other ones either. I hope you can ride it out until you get to high school, then maybe things can open up for you. I got pushed around throughout school, but made it out unharmed. After I graduated I didn’t have to see those people ever again. Things are much better afterwards. People you work with can’t get away with acting like punks. They hopefully grow up and realize they don’t rule the world. My advice to you is to never give up. School is temporary. Life is much longer than your school years. Do the best you can and don’t let people change you for the worse. Be kind, even when it’s not easy. It will be more valuable in the future than you will know.
Wishing you well :-)
