There are three levels of suffering. They are ordinary suffering, suffering produced by change, and suffering as conditioned states. Suffering caused by birth, old age, illness, and death. Pleasant conditions certainly will change. That's suffering there.
Nothing happens by itself.
Whatever happens must rely on something else. Taking away that something else, the outcome will be different. So, you can't do it alone or it won't happen by itself. Craving for pleasant experiences, for material things, for eternal life or death. That something is ignorance.
