Can relate, I've suffered with chronic pain for over 10 years, but because I'm not 300 pounds, refuse to let it bring me down and go on disability and I drag myself to work everyday, most people think that I'm exaggerating or even lying about my symptoms, so over the years I've quit even talking about it.  But it's ok for a fatass to bitch and moan about their knees and back from carrying around their extra weight, I don't get it.
