I Have Social Phobia

I went to attend a briefing session for some sort of tender document for some projects this morning. I was already worried about attending it since days ago and was nervous before going this morning. My fear was meeting people I know but are not familiar / friendly, especially my classmates working in the same department. I was afraid that they would see me and gossiped about me that I looked tired, weird, etc, and then it spread to the whole class even to those working elsewhere and has not seen or contacted for a decade. I was also afraid that they would ignore me even they see me there; and then I was afraid that people would ask why i didn't sit with my classmates, etc.

I don't like those classmates of mine, they were mean and always talked behind people's back and things were probably made up by them; we just happened to be in the same class but we are totally different and don't get along. But I still worry now working in the same department with them.

Luckily those bitches didn't come to the briefing.

Nevertheless, maybe I have over-reacted towards/over-estimated their poor behavior.
