Sometimes "I"

Sometimes I have a hidden dark side to my personality that scares me. I let myself go where I would completely judge another person if I heard they did the same thing.
Sometimes I do really stupid things, not by accident, I know already what I am about to do is stupid but continue to proceed anyway.
Sometimes I don't know the person inside anymore, he is not who I want to be and I dislike a part of me, almost as if there are two people living inside the same body.
Sometimes I get so careless from not paying attention that it gets to the point of being dangerous and I am ashamed of my own stupidity.
Sometimes I know what I should do to make my life better, yet put it off repeatedly, for no reason other than it is easier in the moment to do nothing. I often think about changing to become a better person, then follow the same routine and still expect results.
Sometimes I hurt people that I love, a test I think to see if they will still love me after.
Sometimes I can be so lazy that if anyone worked for me as such, I would fire them. I expect more from other people than of myself.
Sometimes I like when I hold some kind of power over a person, it can give me satisfaction when someone fears me.
Sometimes I feel like I am a bad person, that people don't really know me and that I do just enough good things to fool nearly everyone.
Sometimes I feel the person most out to ruin me, struggle against me and be a major threat to me... is me.
