The intern nurse let me into his body. What novel is it?

I'm sorry I didn't say I wanted to control my body. My parents spend too much energy on me, which makes me sick. The less blessings I get, the less I want to stay away from books. Unlike me, I regret my parents and my grandson, and I need answers. I miss the kindness of my parents 18, but my remains repay me. I hope to help them not to go my way. Masturbation, loss of life.
