We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Most people have at least some degree of this potentially life-damaging fear. Oftentimes, the fear is justified because it is likely that many people will not find us interesting, appealing, or worthy of relationship (boo-hoo), but sometimes our fear is indiscriminate.
Faking confidence isn't a bad starting approach, but the real trick is to improve one's rejection tolerance and that can only be achieved by enduring rejection.
OK, when I was a kid I feared rejection but now that I'm retired and enjoying life and travel I fear acceptance/inclusion. I find myself ignoring people in public so that they won't try to strike up a conversation because I got things to do. Life is good and I'm enjoying and no I don't want to hear about your drama or grand kids. I have even taken advantage of my age and acted as though I don't hear people who talk to me. Just keep walking and don't make eye contact, that's my motto.
