^ All good points.
I will add that if you want boys to be interested in you, then you should first be interesting to boys. At your age, though, the kind of things that boys are interested in tend to involve "proving their manhood". This means that they are likely to be interested in any girl who doesn't mind having a reputation for being "easy".
Don't go there!
Instead, try to cultivate a talent for the arts - literary, musical, performance, or visual. Try also to cultivate your mind - learn a technical skill (electronics, mechanics, et cetera). Work on your appearance (I don't know what you look like, btw) - a healthy complexion, clean hair and clothing, and a healthy figure will catch a boy's attention. This does not mean that you need to look like a cocaine-addicted fashion model or one of the Kardashian sisters. It means that sickliness and obesity are two extremes to avoid.
Cultivate your attitude (again, I don't know you) - be cheerful, outgoing, friendly, and nice. That last one is important. Avoid gossip and angry speech. Avoid "suggestive" banter, too. Focus on the good in people, and don't complain needlessly.
Hold your head up, smile, make eye contact, and treat the boy you are talking to as if he were the only boy in the room - don't be distracted, but treat everybody well. Stand up for those being bullied (even if you don't like them, either). Be generous, but don't let them take advantage of you.
I could go on, but this should do for starters.
