We often overlook details that might seem inconsequential, but they are not. Taking a little time to sort out our thinking about this or that can be well worth the effort.
When we suffer illness it is usually transitory, we get better and move on. Sometimes it isn't and that can engender hopelessness. But that can be transitory too, if we handle it right.
