I'm mental

You didn't need to do that. It didn't aid you in any way or bring you satisfaction or make your life complete. In fact it could potentially hurt someone in the future or annoy them intensely. So why did you do it? 

I was walking home at 1:45 ish last night and I pushed a plastic bottle of a railing. That was what I though after I had done it. I don't know why I did it, I just felt like it. I get thoughts like that on a daily basis and it creeps other people out when I share them. 

A week ago I was in a lecture hall and I had the thought of maybe slamming the person infront of me head's into the desk. I didn't obviously. But I could of. I had never met the girl but I wanted to. 

As humans we have strange moments like this but most people ignore them and move on, never to speak of them again. I however, sit and contemplate the meanings of these things and have decided I am probably mental and should be locked up. But only if I actually acted on them insead of just thinking when I'm in my room on my own.
