Guys I think I ****ed up

Right this is a bit of a rant but I also don't know what to do.
This friend of mine thinks I'm avoiding her and now hate her which isn't true right? I just don't want to be as close as we were but I don't hate her!
I just feel really bad bc she left our friend groups gc apparently bc of me and we have to go on a school trip together and it's going to be so awkward if we font get on.
I just don't know what to do and I kind of want to cry about it I've messaged her saying that I still want to be her friend but idk when she'll read it, respond or even if she will!
Help please what do I do?

Give her some time to consolidate, she has to accept the idea that you aren’t into being really close friends.
Plus, don’t feel bad about her actions (e.g. leaving the group chat) as she decided this on her own - plus it’s a bit melodramatic if you ask me.
Moreover, when the time is right to talk once again, explain with open communication with how you’re feeling. Don’t let this affect your mood!
Hope everything will get better for the both of you.

Ok update she wants to still be friends but her other friend told her I hate her so I'm going to talk to the friend as well to sort out the misunderstanding so hopefully it works!
