End of High School

So is anyone else sad that high school is going ot be over in... less than two weeks?

I mean, sure, yeah we've all said it.

"God I can't wait until I get out of this place!"

"FXXX Burroughs!"

"I HATE IT HERE"

blah blah blah.
I know. I've said it. Even weeks ago I said it. (esp. about a witch bitch named ca.....) But honestly, as our high school life draws to a close, I feel sad. It isn't really that high school life was the best times of my life. I mean honestly, I had a pretty bland high school life. Freshman year had football of course, but I was never really close with most of them. Sophomore year, the same. Junior year I was just... there. Senior year I was largely overwhelmed by the work I had to do. But the thing is that you cannot have it again. It is lost. And I get these frustration and panic attacks that I really haven't done much to make lasting memories in High School.
Basically, I'm sad that I'm losing opportunities. And any passage of time, to me, is saddening. Perhaps this is also because that I tend to largely live in the past, and that is how I look at the present and the future. It goes in line with my love for history come to think of it. Anyway, as I said, I tend to look at the past a lot. And I somehow expect to see that all these people, relations, even buildings and such will not change  at all. But the reality is that everyone changes. And somehow, I cannot accept that. Which makes all this change in everyone just more saddening. I know I will not see most of them the same way again.
Hell, I may not even see them ever again. Isn't that scary? All these faces, personalities, tendencies that I see around will not ever be the same! Although in my memory, it will be fixed at this, or sometime in my Jr. Soph., Freshman year, even though those moments may have been the most insipid, insignificant moments in their lives.
