Mad at my ‘best friend’ for making a decision for me

Okay so a few minutes ago I got put into a group chat with a few people I knew. I ignored all the notifications until my best friend said ‘why’s my bestie on here, she’s too innocent’. That peaks my interest so I go to enter the chat and say I’m not innocent, and she removes me. She asked to be admin just to fucking remove me. You guys may think it’s not a big deal, but to me it is because no one ever talks to me. I thought this would be a great chance to make new friends (those who were added that I didn’t know). But my best friend made a fucking decision for me. Like I can make my own decisions. If I don’t like it, I’ll leave. I’m so pissed right now. I’ve asked her why she removed me but she hasn’t said anything. 🤬🤬🤬🤬 ⬅️ that is what I feel like right now.

Recently our friendship has been going down hill. I feel like we aren’t as close anymore. We’ve been besties for over 10 years, we even share the same birthday. (We are both 16) 😩
