I can’t stop my mind from racing with anxious thoughts- that he’s talking poorly about me behind my back, laughing at me, that my new mutual acquaintances with him are too, etc.

I’d really like to get through this current situation with my dignity intact as I’m enjoying hanging out with these new people and getting to know them better.  But I don’t know how to either ease my concerns, or stop caring so much about what FP thinks :/

Any advice would be much appreciated
