Is it possible to be friends again?

[Cool Story, BRA]

My friend and I were friends for three years. About a year ago something about her changed and our friendship began to suffer. I asked if we could take a break from our friendship. She got really mad and we both said really mean things to each other and eventually ended everything. Plus, I had to unfriend her on Facebook because her posts were really mean-spirited. We're both black and she's become very anti-white and posting things on her wall that could definitely be seen as racist. People from our church and school are often insulted by her posts (reasonably so), and a lot of people have stopped liking her comments because they're really upsetting. She wants to have lunch together this summer (I'm going to college out of state right now), and while I think it would be nice to talk things out I don't know if we can be friends again. I've already made new friends at school, my friends from home don't like her anymore and I don't think she's changed. I'm really not sure. If she has changed, if she's stopped doing the Facebook thing is it possible? If she hasn't would it not be worth it?
