This girl that hates me will be in my homeroom this year. What do I do? I don't hate her.?

This girl that hates me that I have bad history with is going to be in the same homeroom with me this year. But I don't hate her or have nothing against her,yet she is friends with almost everybody in school,and I don't mean Plastic kind of popular girls I mean,I got your back and mean it girl. Anyways she cant stand me at all. And I have a bad reputation at my school because I cant defend myself. But,I just don't wanna make drama. My elementary hasn't been good. My 6 and 7th grade years in middle school have sucked because of drama. So,what should I do about her> odds are shes gonna make everybody against me,even though they already are.
