On my mind at the moment

I'm so tired of everything anymore. I have my good moments. I have my bad moments. Tonight is one of those lovely bad moments where all I want to do is scream or cry or run away. Why? Did something bad happen to trigger an upsetting memory? Was I hurt by someone? Did I just find out devastating news? Nope. Completely the opposite! Nothing bad happened and yet I feel as if I am losing this damned battle I like to call my life.
All I know is that the happier and more at peace I get, the more my mind shoots into overdrive. That's my problem. I think too much. No, wait, maybe I don't think too much, but I over analyze things too much. I also take too much to heart. I let simple little things affect my outlook on what is happening in my life and in doing so, I am driving myself insane.
The most I can say at this point of time is that all I want is to be happy. I know what will make me the happiest. I know what will make me feel complete. I know what will help me get a full night of sleep, and keep me motivated all throughout the day. I know, that what I know is true, and though to some it may seem like some silly dream, some out there fantasy, but at least it's my silly dream, my out there fantasy, and no one can take that away from me. And when I make that dream come true, and live my fantasy into a reality, at least I can look back and see that the hardest part of the trip wasn't getting where I wanted to be, but accepting where I'd been.
