Who are my real friends anyway?

Lately, I have been doubting myself alot. My best friend of five years had a baby and disappeared. Later, I got a message from her mom saying her boyfriend and his family weren't let anyone speak to anyone and I went off on him. Later she wrote me back and told me she hated me and she wished I died. That hurt me badly. She was supposed to be my best friend!!!! Then a few days later my friends got back from Florida. Travis (My boyfriend) and I went to pick them up then my friend Abby decides she just not going to go and didn't talk to us or anything so we left, then later her boyfriend tells us she going shopping with her mom. I was like 'what the fuck? you don't feel well enough to chill with your friends but you can go shopping?' With friends like this how am I supposed to feel. I feel like I have no real friends anymore. I miss my Connecticut friends but they probably don't care about me any more. I've been gone for 2 years. I feel hopeless, I NEED a friend.
