Sudden writing prompt
God has finally answered the prayers of mankind. To each sufferer (mentally or physically), he bestows a superpower to help solve your problems. Blind man gets X-ray vision, people suffering from insomnia can now control their own and others' dreams and etc. The strength of the abilities depends on the amount of suffering of this person.
MC who really considered themself a happy person receives God-like powers.
And now they somehow have to deal with that.
