Don’t fit in?

At a friend’s.. relaxing kind of not in a healthy manner. I could of just want to leave honestly. Maybe it’s just wanting to run from rejection.  Tried to open up to somebody about what is going through my mind and my friend shut it down. Her reasoning is because I shouldn’t let a stranger in on my personal life. Maybe she’s right but it didn’t feel good. She offered to tell everybody to not come over and just let us talk, but being told to stop a conversation felt a lot like rejection for who I am. Maybe it’s just in my head or maybe my hurt feelings are valid. I wish I knew what to think and could trust it.
