Re: Too loud club makes you agressive?
At a club, you definitely need to be louder and have a higher energy level, especially if your target is already in a high energy state. So, I'm not sure what you looked like by being TOO confident and TOO aggressive. I can only imagine something really wild and violent! ... which of course would not be congruent. But you should receive your friend's feedback and next time be aware of your energy level, and tone it down one to two notches and see how that works.
The thing is, you said you got anxiety when your friend left. It's very possible that when you get nervous, you get louder. I have seen that happen a lot. Different people react differently to anxiety. Some get quieter, some get louder to compensate - since you are in a state of fear. So keep that in mind. Take deep breaths, stay cool, and match the energy level with the group.
The world is your matrix. You control the strings.
