How Do I Deal With Losing My Best Friend?

[Selena]

This past week I decided to stop being friends with my best friend. We're just two completely different people now. She wants to have sex with her boyfriend and cuss, and just not give a f**** about life. And, I am trying to better myself. I try to go to church and not get involved with stuff like that. It wouldn't bother me as much if she did things if she didn't do them around me even when I've asked her not to. I've felt so much better this week without all of her drama in my life, but I can't help but feel a little sad about this. Everything was going great until she messaged me on Facebook today and said that she was going to kill herself and she kept talking about how I was such a bad friend. I know she's just trying to make me feel guilty, but it worked. What should I do? How do I deal with losing my best friend?
