Excerpt from Psychology Today: (click for entire article)
In May of 2001, I got sick with what the doctors thought was an acute viral infection. But I didn't recover. As the months went by and I didn't get better, I felt as if I'd entered a parallel universe that I didn't know existed. One reason this universe is largely invisible is that many people living with chronic pain or illness don't look any different from those around them. We simply don't look sick or in pain.
I should qualify that. The people who are with us all the time know that we are suffering. They see those subtle differences in our demeanor when our symptoms intensify. These are our caregivers (called "carers" in many countries) and they inhabit this parallel world with us. At the end of this piece, I'll talk about the unique challenges they face.
