I am majorly depressed. But I cannot deal with one of my "friends" anymore. She is incredibly rude and hurtful towards me. Passive aggressive and cruel. The other day, we went to an out of town festival. 3 hrs in, I was depressed and wanted to go home. She drove though. I expressed to her I wanted to go home, but that we could stay longer if she wanted. She looked at me and said coldly "so we just do what YOU want to do?". So we stayed. At one point, in the car, she said "so how's Laura?". I am not friends with Laura anymore. And she knows that. I asked her why she brought it up, if she knew that, and she said "I don't know, it was a mistake, forgive me?". But she was really smiling a lot when she said it, and seemed gleeful. It was creepy. The last straw, is when she said "I wonder if my religious values play into the way I date.". I have told her about my dating difficulties and regrets. I asked her what she meant by that comment. And she said "you don't seem worried about the things I worry about in dating.". That hurt. I told her I regretted making out with said guy, and she just showed me a catalogue of clothes she was interested in. Completely ignored me. She has issues too. But I honestly don't care. I need to take care of myself.

I need advice on how to end this friendship. I don't want to be mean or cruel or hurtful. I'm not sure if I should be formal about it, and tell her I need a break. And tell her why. Or just block her number? Or ignore her messages. I don't know what's best to do. she gets mad easily and won't take it well I'm sure.
