<human>: Give me a shortened version of the text

A year or two ago, I was very well known amongst my peers as someone who was jovial, enthusiastic, helpful, caring, nice, and pretty much all positive things. I enjoyed talking to people and enjoyed their company. I was smooth with the ladies. 

Today, I hate people. I hate everything about people. I do my best to avoid any social interaction. I do like certain people, and like hanging out with them or talking to them. But I'm no longer. I've become a mean, dickish asshole. I've become selfish. I've become anti-social. I prefer being left alone to myself. 

I want the old me back, but I'm somewhat comfortable with who I am. I do prefer being alone, but I do miss the old me as well. I don't know how to find a balance. 

I'm crushing on a girl, but I don't even know how to talk to her. We do talk, but not much. And I just feel stupid. I feel inhuman, I feel like I don't fit in with everyone else. Every time I watch Dexter, I can relate to him. But I've never hurt an animal or physically hurt a human. I've not gotten into a single fist fight all my life. I just feel comfortable watching him. I feel like him, unable to make connect with others. 

Hell, I don't feel happy at all these days. Even when I smoke some pot, I feel calm and peaceful. But not happy. I want to be happy and content.
<bot>: I hate who I have become, but I'm comfortable with it. Yet I do want to go back to the old me.
