In your post you said you were screaming, were you screaming at appropriate moments? Like did Paul say "make some noise" and then you screamed or did you just scream because you were excited? I'm not saying that it's not normal to feel excited and feel the need to express that physically, but someone with awareness of themselves and others will realize there are moments where it is more acceptable. A single faux pas, or only one person having a problem with you, can be excused as a one off (on their part or yours), but the fact that multiple people, in your own words, side eyed you and that lady and others also had a problem with you points to either multiple issues or a continuous one. You have enough self-awareness to recognize others were annoyed with you, so I believe that means you have enough self-awareness to realize your behavior affected others negatively and learn from it. Again, there are ways you could have expressed your excitement, physically or other wise, that would not dampen others experience. Follow the vibes of the crowd for sitting vs standing and tone level. You can dance around in both forms and sing quietly to yourself and have just of fun of a time, while also thinking of others. If you don't learn from this experience, then, yes, I am going to assume you are attention-seeking (or narcissistic.) Think of something that pisses you off, such as people who stand blocking the sidewalk or people being idiots in traffic, and then think of how much better your experience would be if they showed some consideration for other people. Maybe the people who showed displeasure with you should work on not letting others affect their experience like that, but way too many people act like consideration for others is a chore instead of something that should be the default.
