Alright, I feel compelled to put this whole "cool crowd" thing to bed. (FB to-do about it today. I didn't get involved. I just judged.)
If someone spends even one millisecond wondering if being seen interacting with another person will make people think less of them, they are not part of the cool crowd themelves. They are rather, suffering from deep-seated insecurity and would be better off working on fixing that than seeking out "cool" people to stand next to.
In fact, there is no cool crowd. There are people you're drawn to and people you're not.
In all candor, when I learn that someone doesn't like me (different tham being neutral), I first check my own actions. If I'm comfortable with them, I then merely assume they have "issues". (And acknowledge that my own may come to light later.) If it's someone I care about, I hope they get better. If it's not, I just don't care.
That being said, I totally agree that I have things to work on myself. I'm happy to report progress in some areas.
For just one of several recent examples, S handed me a couple of CDs last week that he thought I'd like. He was right. I genuinely did. (Especially Brandi Carlile, but Stars is in my CD rotation now too.)
A year ago, I hate to admit, I would have spent an embarrassingly inordinate amount of time wondering what it all "meant". What did he really mean?!?
I've healed enough of my own issues (anxiety, "not enoughness", lack, etc) to just appreciate the fact that he thought of me and thought I'd like them. I've enjoyed the music. I like knowing that he thought well enough of me bring them and give them to me. That's really as far as I've gotten.
See? Not always perfect, but willing to own my issues and fix them. And standing next to someone or avoiding being seen with someone else isn't going to fix them.
Love yoursef. And if others don't, that's their problem. Don't get defensive or angry. Wish them well and a speedy recovery and move on with you being you.
