Why are many of my posts on Monday?

Today is kind of a weird day for me. It is Monday October 24 of the year 2010. My left wrist hurts like a motherfucker. I kind of have a weird feeling about people. People I thought I knew and liked, i.e. my friends, i seem to not recognize them. I kind of feel like I do not know anyone anymore. I dont know who I am. What I do. Why? Or anything like that.
Sometimes I feel like I know what I am. But then come these days that make me start from zero again. I forget my reasons, I forget lots of things that made me who I was that day. If there is anything out there that can explain what this is, I wish I knew what it was. But then again, what use would it be? I would forget once again, plus I have never been good with definitions or titles.
I dont understand names, titles, definitions.
If memories make us, then I really do have a problem. I can only recall certain things, on only some days. I change all the time. My memories change all the time. They never seem constant.
What am I?
At one moment I am a friend, at another a healer, at another a savior, at another a musician, at another a poet, at another a sick minded, at another a winner, at another a winner, at another a killer, at another everything, then again i turn into nothing.
I learn things, i love learning. I know that. But what use is it when I seem to forget those things that i learn.
One thing I do recognize, is that for those short-lived times when I see reality I am happy. For those that I cannot see I feel hopeful and challenged for I want to break free.
I want to break free of everything.
I dont want to have friends.
I want to know the reasons behind my behavior.
Right now, memories come back to me of a place where I was, a place where i still am.
Maybe life is bound to change at all times, nothing constant. Always moving, nothing the same. Extreme changes. One day I will go back to that place of stillness. Of warmth. Of brightness. Of innocence. Of knowing about my whereabouts.
But until then I suppose I must play along in the game, I must keep changing. Time is everlasting. As well as me.
Maybe one day I will stop and know where, why, and what am i.
