I feel worthless and ugly?

looking back from the pictures at prom my friends look all glamorous and stunning, i just wanted to feel special for one night but htey all looked better. I feel i dont play a important role in life im jusr average average looks average personality and i feel boring it looks like evryone else is having more fun. The boy i like gave hints or maybe i just read to much that he liked me i started to fall badly for him now hes got a girlfriend and i cant watch them together it makes me feel like dying im not clever or talented in anyway so overall im a crap person maybe im nice and polite but where does that get you in life?
