15 and tired of life..

So to to make it as short as i can..im a 15 year old girl living in a tiny town out in the middle of no where, i have a few friends that are close..but i just finished my freshmen year, and im back almost all my credits because i missed to much school, when i used to get straight A’s the middle school.. because i couldnt even handle getting out of bed everyday, and facing all those happy people, with there boyfriends and girl friends, and there cute clothes, which i cant get only because my size..and all my friends seem to have boyfriends now.. and me being fat, ugly, and now stupid for failing fresman year, have no one.. my parents dont give me the time of day.. and i just have no one.. i want so badly to be in love and be loved back? i know im ‘only 15’ but theres just somthing about having a life. with a husband and kids that makes me want it so badly..i’ve never had a boyfriend.. which is almost unheard of here.. never been kissed, never had any of that.. and my friends are all so pretty, and im just not..i try.. i wear makeup do my hair, its not like i dont put an effort.. it just doesnt help and how quiet i am i guess.. im just tired of life..not having anyone who shows me any affection or love.. im only 15 and i cry myself to sleep alomst everynight out of fear for being alone forever..i cant live like this anymore.. all my friends are out with there boyfriends today, or out at a party and im home, alone.. doing nothing with my life..i just dont want life anymore..I had one guy i had grown to like.. and i got up the courage after a year of having such a crush on him to tell him how i felt thru facebook..he never even replied to me..with even a simple ‘oh i dont feel the same sorry’..no one gives me a glance..i just dont have purpose and i hate having an empty broken feeling all day.. i just want to go to sleep and never wake up..im not looking for sympathy..i jus need to know if anyones felt like this and how to get out of it? i used to be a happy kid..but i gained weight..and then suddenly everyone was talking about love.. and at first i didnt care much..and now its all i want..and no one in the world wants to give it to me.so many girls complain about being ‘heartbroken’ after a break up.. or being ‘fat’ when thers not even close.. and at least they can say theres someone who would want them..they dont know what its like to never had even experinced it.. at least they got a chance.. its horrible to live in a world where the way you look will decide your fate in life..a few of my friends treat the boyfriends like garbage..but because they’re pretty, the guy stays.. i dont understand..
