Revelation & Suffering

I was on a chat site one time and someone quoted a Scripture they said was from Revelation which said something to the effect "God is responsible for all the suffering that happens"

is anyone familiar with this? I skimmed over some of that Book on a website, and I did not see it. Does anyone know it offhand? I cannot really read Revelation, though I have read it, but it makes me feel anxious. I have mental illness, so I'm just trying to be safe.

I know there's one in Isaiah or something that says God creates light and darkness good and evil etc etc, but this one was from Revelation. I know that God does not do evil, of course.
