everything in my life is going wrong

Abbie
My ex gave me strep throat. He asked to meet up on Sunday and I stupidly went. He wanted to hook up and I fell for it but he stopped half way and said he couldn't do it because he "still loves me". So I've been sick all day. And I get a phone call waking me up from a nap from a friend cussing me out. I look at my texts and my ex best friend is accusing me of sleeping with her ex boyfriend. She then threatens that if she sees me she will kick my ass. I didn't do any of this shit. Then my ex boyfriend snapchats my friend asking her to come over and hook up. When I dm him on instagram asking him about strep I tell him to stop messaging my friend and to infect some other girl with strep throat. He blocked my number and instagram after that. I've lost every person I had ever been close to very recently. And when I think things are over and done, they end up popping back up. I've never felt so low in my life. I don't know what to do with this feeling.
