Another fat psycho checking in. 
I’m not sure what to think of RexDart at this point. He sounds an awful lot like an angsty teenager in serious need of something outside of his pampered suburban upbringing.
Rex, as many women have stated before… the poor, poor pitiful me thing is a HUGE turn off to women of all sizes and mental balances.
Dropping 50lbs will not make cute college girls want you.
Trust me on this one… I could DEFINITELY stand to lose 50lbs, but you know what? I’m also 24 and I’ve never hurt for beautiful men who care about me and appreciate seeing my boobies all the same. Some of those men have been chubby, some thin, some well built, the current one is a bit on the lanky side, but easily the most beautiful boy in the room most of the time.
And I have alot of girlfriends whose sentiments have almost mirrored your own. Some of them can’t seem to figure out why I get the cute guys and they get, well, nobody… despite their very obviously better body.
If you suck on the inside, there’s no magic look that will make someone fall for you.
God, I don’t even know you… but even BEFORE the “fat or psycho” bit, I knew that you’re the kind of guy I steer as clear from as possible.
As someone mentioned above, you come across like the type to be needy, jealous, possesive, etc.
It doesn’t matter what you look like, those qualities will ALWAYS be ugly enough to drive people away.
My advice? Quit spending so much time alone and concentrating on how shitty your life is and DO SOMETHING. Anything. The Peace Corps was a nice idea, really. There’s a big world on the other side of this bubble of self-pity you’re floating in.
And don’t worry about ending up with a heavier girl or a “psycho”. No one wants to be with someone who doesn’t find them attractive. By the same token, you really should consider being less vocal about your distaste… as ALOT of women (thin, heavy, perfect, etc) will immediately shut you out and consider you an insensitive prick for assuming that fat, psycho girls are somehow inferior to the rest of the population.
Good luck.
