I like posting random material here because it lets me document my everyday thought processes.
I used to be really shy and insecure. I didn't even have friends to go hang out with until high school. Relating to people was very difficult. I spent my time trying to be good at things--sports, academics. I self-separated; didn't have a girlfriend until I was 19.
In high school and college, college especially, I made close friends and was social. That lasted for a while. Now I'm past the point where I'm anxious in social situations. But on the same hand, I choose to not be with people much of the time. I am solitary in nature. If I have to be with people all of the time, like for a whole day, i.e. 14-16 hours, without reading or headphones or anything, I blow up with anger eventually because it just takes a whole lot of energy for me to be in social situations. I feel guilty because the cause of the anger is that I can't control my thought process when I'm with people as when I'm alone. I like my self-company; call it narcissism. It's my nature.
It's really hard to bounce back from embarrassment. But one's in control of it. I once gave a speech as a freshman in high school, and felt really embarrassed about how it went. Not only did I actually get a good grade, later on, I realized that peoples' short term memory forces them to forget 99.7% (I estimate) of daily interaction stuff after a week or so. Think about it.
