<human>: Can you condense the text into a few key points?

I'm very uncertain about whether I should continue socializing with my primary peer group; at first, I appreciated being surrounded by such a large bunch of individuals, but gradually, I've begun to realize that my severe social awkwardness acts as an impediment for becoming truly integrated into any social circle. My immediate associates likely just chose to tolerate my presence out of pity, sympathy, and concern, and the position I occupy in this aforementioned group is very much akin to that of a fringe member (overall, the others tend to treat me like a child, and I constantly end up getting rebuked or reprimanded for my many errors). 

To make matters worse, I developed an unrequited crush on a girl – despite her kindness, I never saw any indication that she liked me back, and even if she did, other circumstantial factors would still make it impossible. It's so idiotic that I'd develop such a selfish emotional attachment – I've intentionally rejected every bit of compassion that she's tossed my way in hopes that being cold/dismissive would prevent her from learning about any of this, and although I cannot know for sure, I believe she did eventually figure it all out due to a rather humiliating incident that I'd prefer not to expound on. 

From a purely objective standpoint), my presence has just added stress/anxiety to the group, and I don't feel that I've been of benefit to anyone else (just to be clear, words like compassionate, friendly, or gregarious couldn't exactly be used to describe my personality). My life has always been pretty screwed up (if you want further details about that, I'd recommend PMing me), and I think that my closest friend out of the group (the guy who introduced me to everyone in the first place) has begun to care *too much* about how I'm coping with it all. Honestly, I don't want him to feel responsible for whatever fate eventually befalls me (after all, he's done everything that he can to help), and I currently believe that departing from the group might be the best choice available to me.
