Dude, being 16 is no picnic, it is one of the toughest times in life,
for everyone. Know that probably 95% of your peers have/are dealing with the same issues, I assure you.
>>I feel like I'm going to explode.
Exercise, do something. Walk, run, lift, something. At 16 you're a nuclear furnace of energy, expend it/channel it in some physical activity. Exhaust yourself. Nix the video games and TV. Get outside.
>>I despise the way I look.
What can you change? Work on what you can change, accept that which you cannot. Realize the media sours our feelings of self-worth, in that if we all dont look like Paris Hilton or Brad Pitt, then we're ugly. This is simply unrealistic. We're all different.
>>My fear is that I'm going to be alone for the rest of my life.
Difficult to imagine, but life at 16 is a world away from what you'll be experiencing in years to come.
And really, being alone (glad you said that instead of 'lonely') is something you may come to appreciate. My times being alone now are something I look forward to, to unwind, decompress, etc...
Go a day at a time. Work on yourself, forget everyone else.
Go
