Mr.Black, the only way you walk away from this one without looking worse is to come right out and say something like:
'Yeah, I've been a total dick lately, totally making crap up about my pathetic, hum-drum life that apparently you all saw through immediately, and I capped it off by making threats to each and every one of you when you called me on it. My first reaction was to try to backpedal with the ol' "It was an experiment" ruse, but this too you all saw through, so once again I resorted to threats. Finally you all turned the tables on me when it came to the Con issue, and I belatedly realized I might not be able to attend the Con (not that I would have ever shown up to back up 1/10th of what I said) while making such threats, and it also occured to me I might actually meet up with any one of you on the street. This thought alone has kept me awake shaking at night, the knowledge I am totally incapable of defending myself having paralyzed me socially for so long. So, accept my apology, and understand it is I who wouldn't have the male genitalia (man, do I ever have an obsession about those! Mmm-MMM!) to back up my words face-to-face.
It's not as if this would be a revelation to the rest of the HTC crowd as it would be cathartic for you.
Edit: speiling. might hapen agin, to.
