the end of an old or the start of a new chapter..?

Wow, what a way to go! yesterday was not one of my best days in the world, but no need for explanation, just know it wasn't "the best". I was tired all day and at work I was in a daze, not just from physical faigue, but from emotional and mental also. i've been super-busy with studies because I just started going back to school this fall, but i expected "school-stress". there's a part of my brain that i had already trained to get ready for it. I knew working while in school was going to be really difficult as well, but again, I had already trained my brain to get ready for it. With just those 2 things in mind, i was set on moving forward and doing what i have to do to get through this. I felt I had all the support I needed. what I didn't expect was the support that I wanted. I've been dating this girl for a really long time and out of nowhere I feel as though she's just not that "important" in my life like she used to be. so, with that said, while at work I was in a daze just going through the motions because I could not help but think how much life is sucking just thinking of what I'm thinking. I went to bed wondering "is this it"? well apparently it was....I woke up this morning just running some errands and then it hit me "this can't go any further" I hurt inside just saying it to myself. well, we got together to talk about "us" and what turned out to be what used to be "us" is now "me" and "her". we broke it off..:/ now all i have left is pain, but it's just day 1.
