Hi, I found your link through Haddayr! Just wanted to chime in and say this post reminds me very much of myself (always classified as an INFP every time I've taken the Myers-Briggs, too, by the way, and have taken Paxil). I had insomnia and an ulcer when I was a kid, largely I believe over anxieties related to school and having to be around other people in masses; the ulcer developed the summer before I started junior high. I used to make lists of people (other kids at school) in front of whom I had never had a humiliating experience, and I thought of those as my "friends." Most of them I had never spoken to. But if I had never been embarrassed in front of them, or been made fun of by them, they sort of counted as friends. There was more. I created a similar post to this one on my own...well, I don't know if it was for the same exact reasons. I was having extreme anxiety about the forwardness of creating any sort of space where other people would read my thoughts, and the lack of control over their reactions to me that would ensue. I have developed a lot of defense mechanisms in response to my shyness--so many now that I feel like my shyness is more or less completely masked in public. But the cost of it is that I am exhausted all the time from the effort it takes me to present this face to the world. Well, I should shut up now. I enjoyed reading this post.
