I can be super sensitive on certain issues, and I am very private in real life.
Low self esteem and arrogance. Yup. Check.
I heard someone say in an AA meeting, "I can think I'm better than you and then in the next minute think I'm worse than you."
I'm not sure how much of that is alcoholic thinking and how much is just human thinking. I'm pretty sure everyone battles that at times.
I have fear of public speaking and job interviews, but I've trained lots of people in classroom situations, and I made 500 skydives. Some fears are hard to shake and some I don't have. We are bundles of contradictions, we humans.
