I want to take a break from a friendship without telling anyone about it
That can be tough. What do you think will happen if you cut them out?
I don't like to think about it, but I think she is very perceptive.
It's okay to withhold your feelings from other people. You can talk to them when you are ready.
That's just how I roll though. I don't like to feel vulnerable as fuck.
Yeah, you don't really need to let out your innermost thoughts to everyone. You deserve some privacy, but don't you think your friend will worry even if you think she'd understand? How about just simply telling you want to be alone for now, so she won't get stuck thinking?
