You know when this is relatable

Ok finally a book i can rant in safely. I am an utter mess. I think i might have just ruined everysingle one of my friendships in one message.
The thing is one of my best friends asked me out. And i thought i would give it a shot. But i realised i am not ready for a relationship yet so i told her and she acted really upset. I know all of my friends would protect her and that i got a bunch of my friends through her. Im scared they are going to leave me. Help. Its hurting.
