I Am My Own Biggest Villain

I have been living in the virtual world I created. When I left the virtual world, I remembered that I was a patient with mental illness. I was extremely dissatisfied with the fact that I was trapped in this diagnosis room. I tried every means to force them away in order to prolong the time I was alone and continue to be immersed in the fantasy world. Until one day the police came to me and the case was that I killed "myself".
