Is Life Going by too Fast?

So being in college, this one of the most important times of our lives. It is the base to our life. This time right now will define where we will be tomorrow, a year from now, 5 years, or even in fifty. As any other college student would know though, that this time in life is by far the most stressful. For me, I've been in advanced placement classes all the way through high school. That was stressful. My friends were having fun while I was worrying about my homework. Sooner than later I began to not care. Why I didn't I wish I could say. I think it's because I've never seen the point of all this hard work for a life full of prosperity that will never be reached. Now that I'm in college, it's the same scenario. My grades are awful and I'm growing back into my depressed state of not carrying. I don't know what I want to do as profession. Why should I be working hard for something that I don't even know if I want?
To top it all off I lost my girlfriend not too long ago after a year's worth of being together. That hit me in the face like I crashed my car into a brick wall. I don't see half the friends I'd like to see on a regular basis. All I do is live my life day by day just to see another weekend. It's not an appropriate thing to say, but I simply live to party. The only time I can ever feel happy is on the weekends drinking with the people I love and never get to see.
This all brings me to a question though I just thought of before I started this post. Is life going by too fast? Like I said before I live for the weekends, but it's like every second I turn around the weekend is already here. Every week I think about it too. I think "That's another week already gone." Feels like yesterday I was one game away from a state title in football. It feels like yesterday I was receiving my High School diploma. In fact it feels like yesterday about too many things in life. I just wish I could answer my own question of "Will it be too late before I want to change?"
