Everyone suffers at some point in their lives. For some it may be every day, no matter how subtle. It could be because you are trying to be someone you are not; you may be idealizing a life you do not have; or it may be because you are struggling to put a roof over your head or have lost a loved one.
Whatever your level of suffering, it hurts. And it will continue to hurt indefinitely until you do this on the next page.
