I'm a very private person, when I talk to people I'm generally reserved and don't say much about me, my life or opinions. I have anxiety and depression which also holds me back socially, but sometimes I meet someone who I feel I can relate to and I make a genuine connection. After the interaction is over if I think about how open I was I feel disgusted. I used to say I felt embarrassed, but upon further reflection that word doesn't fit the feeling I feel, it's more regret and disgust. Almost like someone saw me naked or I exposed a weakness. It also feels wrong, like immoral. 

I'm a big fan of analyzing things for self improvement, and this is one that's stumped me. I like to make analogies that help me deal with complex psychological problems. What could possibly be going on that I'm not realizing? Have you experienced this? What are your guesses or insights?
