I'm currently on vacation, and my major occupation is to spend my whole day in front of my computer, while other people (the socialy active people) are enjoying the precious time they have as young and energetic humans.

I wonder where I screwed up. I don't seem to have had a traumatizing childhood, nor genes that prone me to social illness, but the fact is I can't stand people. I don't know who to blame : them or me ? Everytime I'm on their vicinity, it's like all my strenght is being absorbed. What frustrates me even more is that, sometimes, very rarely, I happen to be very sociable and cheerful. So I can be like that, but how ? How am I supposed to maintain that state long enough to finally enjoy life ?
