The heaviest, nastiest recon ever for me was with Stark, about a month in. Three days in which I wanted to die and had the worst headache of my life.
I think you are on the spot with the why.
That time I was so scared and felt so exposed, I even deleted my journals in here.
Now a year after I feel totally different about myself, introvert is a word I no longer identify with… quite the contraire… I feel I can easily talk with anyone, whenever I want… and I can be very seductive with my words.
