I Have Forbidden Divine Weapons

(Aka: I'm mentally ill) The world is gray, happiness is fake, and even breathing feels tired. Shen Shen was trapped in the abyss by depression, misunderstood, and deliberately "cared for", thinking that he would eventually rot until death. Until he discovered—— All despair and pain are not only symptoms, but also the power blocked by the world. Here, Mental abnormality is a superpower. If you are depressed, you will become a forbidden divine weapon. He used illness as his blade and pain as his armor, and he went against the will of heaven from then on.
