Feeling Melancholy...

Does anyone out there understand that feeling you get when you look at a picture that either you took a long time or a short while ago and you can't help but feel depressed? Because those happy times are long gone, and you're left to bask in the dismal "what if's" and "should have's."
I had been feeling this way ever since the beginning of the second semester of senior year, or rather, the "beginning of the end, in my case. The feeling must have increased ten-fold, with me graduating last week.
I felt like I was watching my own funeral. The eulogy was given by our valedictorian, all our family and friends were there, watching, waiting, crying, as we tried to hide our own tears. The whole things was just so emotional. The ambiance was stifling.
The strangest part about it all was that it wasn't my friends or my teachers that I found my self not wanting to leave, even though I'll miss them terribly, but one particular person that I, to this day, refuse to part with. A person that all my friends have been saying that wasn't good for me, seeing as how he put me on an emotional roller coaster this year.
If he hadn't saved me during my moment of weakness, I wonder if I would still feel the same way. I injured my knee at dance practice, and two of the dance team girls helped me to the trainer. On the way back down he saw me, and stayed with me until practice was finally over, then insisted that he carry me to my car, which he did, with much difficulty. I was swept off my feet... quite literally.
I wanted so badly to convince myself that he wasn't worth my time. I wanted to convince myself that there would be others. But having that unexpected rush of insomnia, looking through pictures and suddenly running across his face every so often, and remembering that I only have the rest of the summer to be with him, makes me kind of depressed, and wish that long distance relationships had better odds of working out in the long run.
I really wish that I knew what exactly was going on in his head. There are times that I think he likes me just as much as I like him, but then every so often, there is that glimmer of indecisiveness and doubt in his eyes that makes me want to rethink all of my feelings too. I wish he wouldn't give me false hope. I wish there was a clear and distinct answer to all of this... even if it wasn't the one I wanted, I would be satisfied with an answer, nonetheless.
I guess looking at pictures does this to you... It makes you think, remember and feel a million things at once. So, I must take these things as they come, and wander blindly into the future.
