Is this normal behaviour, concerned parent

Living with Maryien

Maryien has some things to write so I will leave it to her now
I may sound like a monster or some depraved freak but in all truthfullness I am just a creature who enjoys the beauty that comes from pain and the peacefullness that comes from chaos.
You may feel bad for this girl having to live with me and all but in all honesty if she didn't have me she would have to live a positively depressing "normal" exsistense, yes it may seem horibble to live with something that wants to consume you alive mangle your flesh and rape your soul but through all this violence comes a sort of refreshingly manic happyness that compares to nothing else. I love who I am I love what I do to the weak. She irratates me so much because she is allways concerned about what other people think of her she isn't free enough not to care she is a soft and timid little thing that teaches me how to love truthfully. I am the dark one that teaches her how to enjoy the unenjoyable.

:letter, to Her
:from Maryien

I find it very hard to talk to you as we allways seem to get into an arguement or you find some anoying way to silence me so I thought it would be smart to just write you a letter, I just wanted to say that I am very anoyed at you today for constantly feeling like you need to reach out to your friends to feel happy I would like you to instead just concentrate on the love God has to offer you and improve your self by finding work and taking some educational courses so that we can eventually have money. It also concerns me how much you are letting yourself be influenced by others that although they may love you have no understanding of your perdicament they have no idea that you are living with me and I will NEVER let you tell them so I feel that you should take more of my advice and perhaps less of theres because although they are giving you advice that will make you happy I am giving you advice that will let you dealve as deeply down the rabbit hole as you can go somewhere were the wind is soft and the people are manic a place where all is well because nothing is where blood hangs from the sky and the flowers smell like candy. I want you to give in now and realize that I own you there is no fighting me there is no point in even trying no one can save you from me because no one will ever know that I am here. Do you even know what I am going to do to you? do you even know where I am going to put you this time? I am going to take you by the hand now, shhh don't make any noise you wouldn't want anyone to know your true self would you? go go now to the darkness and the forever trust me I will show you things you didn't know could be.
Rationality

deep down I know Maryien isn't real I know the only enemy is myself and I even know the only reason I felt I had to create her and believe in her is that I was to afraid to take responsibility for my actions.
