Why doesn't anybody want to hang out with me?

[Diego]

I am a sophomore in high school right now and for the last 3 years I have had maybe 2 people ask me to hang out maybe twice but that's it. I have asked my friends from school to hang out with me, but they all say yeah then cancel plans last minute or say they can't or are busy for that day then later tweet or post a Facebook status on how much fun they had with other friends... I talk to them during school but that's it after that it's like I don't exist to them. School days, weekend, summer, you name it I'm always alone with nobody to hang out with. I don't know what to do anymore. All I wanted to do is have fun with friends and enjoy life, but instead I feel miserable..
