I am in the library writing my diary

I am in the library writing my diary. I am a clinical criminal and my place is in prison to accomplish my mission. I stole a bell that sounds like hell. I want to be detained to end my pain and gain. No pain no gain. If I die tell them then, when the mend of a friend depends on my pen, i tried for God knows how many years, can the ears hear here?, and failed in vain in pain in the rain. Will tomorrow bring sorrow or rainbow?. Share if you dare and care. Thank you.
