I work at a restaurant and I notice that when your energy has a huge effect on people around you and how you communicate.Let me give you an example I generally have a high energy.But I was talking to a girl that I really like and a guy told me that he was with her at her place the other day.My energy collapsed at that point.Like it was intense negative.This happens alot.Its like I'm attached to a certain feeling or relationship and when that changes or I can't go back to that feeling I feel if everything collapses.I am conscious enough for me to stay centered and calm through these episodes.They don't make me as mad anymore I guess because I'm use to them and I'm very strong mentally.But is there a way to prevent this?I try to not get attach to people or certain life situations because of this but it seems like such a hassle constantly worrying about my vibe crashing.
