You don't know pain until you're staring at yourself in the mirror with tears streaming down your face and you're begging yourself to just hold on and be strong. THAT is pain.
Love should be your safe place.
One common factor of chronic pain is the "invisible illness" factor. This refers to the fact that many people living with chronic pain show no visible signs that indicate they are in pain. More often than not, these people may look completely normal. This makes explaining pain and disability a lot more challenging.
