Suicide? Everyone loves a corpse.

If your fat and nerdy, stop being fat and nerdy. Go to the gym, do some excerise or something. But you have to ask yourself whether its worth changing who you are for someone else. Whether you like being a fat computer geek or not. Experience things, if you have great stories, all you have to do is tell them and people will interested. That will help build up your charisma, which will in turn make stories better, more people will like you etc.

Just a suggestion.

As surprising as it may sound, (around here, at least), fat kids actually get decent pussy. Just be cool as shit. If you're one of the coolest mother fuckers the girl(s) know, they won't give two shits that you're fat. Some girls even have that 'nerds are hot' attitude. Just show off some of the shit you know about computers if one of them has something wrong with their computer that they don't know how to fix. Also, in getting to know girls, Myspace and instant messengers can be lifesavers.

1. Get off the computer
2. Work out if you can - exercise! Or at the very least go outdoors and get some sun on you.
3. Change your appearance. Get your haircut to something that flatters your face. Wash your face. Work on a new wardrobe - nothing to drastic. Buy khaki shorts and next time you think about wearing a T-Shirt, throw a casual button up. You can find them for cheap at Old Navy, JC Pennys, PacSun etc.
4. Can't really help as far as charisma. You just have to practice speaking - everyday, try to strike up a conversation with random strangers. Just throw a compliment or comment and see what they say. If they follow it up, great. If not, just be on your way. The most important thing is to not give a shit about what they will think of you. You'll never meet them again, so who cares. Put yourself out there. Take small steps. Confidence is far better than any piece of clothing or jewelry.

murder/suicide/reincarnate as someone better

Assuming your Karma's intact...

Get off the PC, and go outside and DO SOMETHING, preferably something cool that involves guns and camoflage. May I suggest paintball? It'll get you in shape. (Hey, it's helping me out).

Or learn to play guitar. That helped me too! Oh, and get a job.

But really, this might be better for Reinvent Yourself.

Key to Charisma = Confidence and Wits.

Working out helps two fold here. You'll lose the "fat" part, and it'll make you more confident. With that confidence, work on your wits. Utilise your brain in more ways! It's not all that hard once you get the idea.

Reinvent Yourself could probably help you better than S&A can.

ok i should stay outside and do shit all day, and talk to people.. i already play guitar, so i should play it when im inside instead of fucking around on the computer, or work out

Listen to this guy.

Be a nice person, and highlight your skills, but not in a bragging sort of way, in a helpful sort of way.

Those are two keys for fat kids I find.

Mostly be nice, nobody likes the fat kid with the angry fat kid complex.

Oh, and think about the girls you want to go for. What sort of gal are you looking to get?

Kill yourself, now I don't mean like splatter your brains all over the wall you sick fuck. Find out who you want to be, and do away with anything in your life that doesn't fit in with your new lifestyle. Add stuff that inspires you to be the person you want to be. Consider the old you dead, and the new you had just been born. I might help if you baptise yourself. Empty your lung go under water, and emerge with your first breathe. But, be wary of of this practice, sometimes when you kill yourself, you kill everything around you.

Don't listen to this guy, we all have beautiful qualities that do not deserve to be squelched.
