Who am I?

I have no idea who I am anymore. Have I become everyone and anyone? Everyone except myself? 
Was I ever there? Have I got a personality? Did I ever have a personality? 
Is this me writing? Is it for someone else? Is it for you? Who are you? You are in my head all the time. I have no idea who you are but I have a strong desire to please you. How can I please you? How can I get you to like me? I have no idea if you are even real. I have no idea if you are reading this but it doesnt matter. I play my guitar but I imagine how you react when you finally get to hear me play. You will all love me so much. No change that chord, change that lyric they will not relate to that, that will upset them, yes yes yes! they would like that song, they would think it is so clever. They will all like me then. If they see me walking down the street they will like this shirt. Its a bit like the shirt I saw them wearing at the party few months back. Oh wow! I drove past him and I had my music playing loud in my car, it was a cool song I bet he liked it, i bet he thinks more of me now, oh shit fuck shit I drove past her and I had a really shit song on in the car, i like it but I bet she doesn't like it. I will joke and say it was shit when I see her next. I don't know half of them. They live in my head. Constantly trying to please everyone. Blah blah fucking fuck. I hate it all. Their back now, oh this is good writing, fuck off. Seriously just fuck off out of my head. Please just fuck off. They left. Their back! heres johnny! Fuck off johnny. Delete, save, delete, save, delete, save. Fuck off, who the fuck are you? Why do you live in my head? Whats it like in there? good views? good weather? 24 room service? can I live in there now. I want my head back. I was only renting it to you intil I wanted to return home. Im ready to come home now. What? Its me? I was living in there the whole time? But i thought you were them? You looked and sounded like them??? Come give me a hug. You weren't to know what you were doing was wrong. No one showed you the difference between right and wrong. Im here now. You don't have to hide anymore. I will look after you. I will protect you. I will be your loving big brother, I will be your emotionally loving father, I will be your cool uncle. No one will hurt you. You have to trust me. I know your scared but I will never ever let anyone hurt you again. I will rip their fucking eyes out and slit their motherfucking throats if they ever lay one finger on you.
And when your strong enough you can go of into the world. You can start living life. You can do anything you want. I will take a back seat in your life. You will be your own person but I will always be here to look after you. I will always be your friend.
