What should i do?

Ignore them there is more to life then the stupid drama of eighth grade and eventually they will realize this too. But if they do try to get you to hangout with them say that your mom won't let you. If they continue pushing keep ignoring. Don't let them get to you. Girls like that will be nothing in the future just remember that. I hope this helps and good luck in 8th grade. I think it is great that you want to make your mom proud of you.
