Help with being bullied?

[Loolooxx27]

I used to be close to this girl. We fell out over her being racist towards my friends. It won't stop. Apparently I bully her yet she inboxed my friend on Facebook calling me names. She also inboxed me about not being bothered about me etc.. She won't leave me alone. Shes been on a mutual friends profile and seen messages about me being upset about it. I cry most nights and feel like I shouldn't be here. Told the teacher but it's continous. Please help x
Thanks all of you. You all helped. Yes I have blocked her on Facebook. It just gets me really upset. At school I try to be strong but at home I break down. Thanks all of you again xxx
