Life sucks and idk why..?

This might sound confusing but i have always thought i was pretty and popular. but now that i am going into eighth grade i feel like no one and i mean no one likes me. its summer and i have hung out with several people and their not part of the "popular" group. i mean people like them and all but they just arent popular. Now to guys. the past year i have dated alot of guys but most havent been ( once agian) popular. they arent the most hottest guys in the school and they dont get all the girls but i like them. now that i am a big eigth grader its seems that no guy likes me they all lead me on and to find out they dont give a crap about me. and sometimes that can do alot to you. this might not seem like a big deal but sometimes i think i shouldnt even be alive. my parents on the other page spoil my brother and yell at me for the most riduclous crap. i want to yell and scream at them! lifes just not that easy anymore. nnd i dont know how to fix it.. please help any advice to getting to be more popular?
