I absolutely suck at communication too. It's always so difficult for me to my thoughts across to other people, even the few people who know me and I'm relaxed around. I generally prefer electronic communication to face-to-face.
What I hated the most about applying to college was waiting forever in line, surrounded by strange people, waiting to see another stranger who had access to a fair amount of sensative personal information.
My parents as well have a lack of understanding about my feelings and assume I'm lazy, selfish and don't care. As a result, over the years I've become pretty numb to their criticisms.
