Is it normal to be some kind of edward hyde?

Hello everyone,
I'm a man without a name. I don't really have a home, I'm just living at a friend's place that is my own but somehow it isn't. I'm even wearing his stuff, though it is way too large. I'm not very tall; to make it concrete I'd even say that I'm small, especially when compared to my better half. I wear a mustache and a chin beard, am pale and hairy like an animal. I don't know why since I have no clue who my closest relatives are. It's said these are the same as of my friend but I can't believe this.
If we two would be related, then I don't understand why I feel the need to press him on doing what I want and not feeling anything but satisfaction if he does. He said since I have no home I can live at his place and work for him but I believe that soon he wants to get rid of me as he called me a parasite when with his friends.
And I mean I'm not for I don't drink or eat too much and am out at night so no offenses could come from my side. Though it urges me to harm others and destroy. I mean, I've got a promise to be kept that I won't do anything but sometimes things just happen, right?
So why do I come up with Edward Hyde? It's simple. I was once asked if I was cosplaying while I spent time in Frankfurt. Don't know why they came up with it. I'm not too conspicuous by wearing what is now called a business (or butler) dress.
I was curious so I did read the book about half and a month ago, I watched the movies (but was kind of disappointed by most of em) and the more I think about it the more all descriptions do match in some kind.
And, without any jokes made, it made me sad and angry both at the same time. I could've jumped up and down from a cupboard rip off it's doors and throw everything inside out then cry over the chaos I've created.
I don't get anything.

Ed
