Please read (friend drama) need help

So last week I invited my best friend to come to a trampoline park and when I asked her she asked if our other friend was going and I said no then she texted her and said that I was rude when she never invites me anywhere. That day I asked her to sleepover during the weekend and she said that she would love to. I asked her if she still wanted a sleepover and she wasn't answering and she texted my other friend and said that I was on her last nerve. Yes I did text her a lot but I had to know if it was a yes or a no so I could tell my mom. Another time I was in Florida and I had terrible signal so I didn't know if stuff sent. I texted her a lot there too because I didn't know if I ever sent and she did the same thing. She went to our friend and said Maggie is on my last nerve. Then yesterday we got sonic (which we love), a baby bottle pop, and cookies she kept on say how it wasn't good for us. Then she texted her mom and said don't let me eat unhealthy. And she wouldn't let it go she was like sonic-BLT-tater tots-tea- candy- cookies-unhealthy. LEAVE ME THE F ALONE!!!!! She was like ur mom doesn't care if u eat this and I was like no and she was like oh. I don't really eat a lot and I have so many health issues so at least I'm eating. I don't know if she likes me anymore. She's always like did Maggie makeup a lie to our friends. Like WTF. And last night I was like wanna see if all of use could go to the trampoline park together and she said sure and I was like do u think we could and she said we'll see and made a mean face. She's always texting our other friend but never me. And she's always haveing sleepovers with her.

What should I do????? I think I'm gonna have a break from here until cheer because I need one really bad just text her for an hour a day then leave.
