The Tragedy of Graduating High School

So, in case you did not know, I graduated high school last year in 2008. A lot of my friends were juniors in my senior year and now that I have graduated they are now seniors. I titled this the tragedy of graduating high school because the tragedy is, is that now I am alone. Not physically, because I do have a family, but friendship wise I truly feel alone. My best friend is at a party right now and I know that last year I would have been invited by her to go but now, I'm just a memory; not even a thought. So I'm sitting here on a Saturday evening with no one to hang out with, writing this here blog entry to tell the world how this makes me feel. It's like I fell of the face of the planet with my high school friends, and I guess that's why many people go to different colleges so they can meet new people and make new friends. It's not that I haven't made any new friends, but its just that she's my best friend, MY BEST FRIEND, and she forgot about me. I suppose that as you grow the meaning of friendship changes. But if you had a friend whom you thought was one of the best, desert you, how will you be able to know in the future who is truly the best and who isn't? I guess you won't find out until that point in time happens, again. But, I truly am disappointed. I am just overwhelmed with this emotion of being forgotten. It's like I died, even though I am still here, living. I also feel that I can't tell this to her anymore because I am afraid. I don't want to jump to conclusions and I don't want to seem, pathetic. I also feel like I don't really know much of her anymore, simply because I haven't seen her in about a month. But, like the title says, this is the tragedy of graduating high school.

Any suggestions on what I should do? Would greatly appreciate the advice!
