People with chronic ilnesses, especially chronic illnesses that may be terminal, tend to live their lives with a totally different set of perspectives than those who are healthy.
Do those perspectives rub you the wrong way? Tough shit. It’s more than likely none of your business. I don’t have a bad attitude. Don’t mistake my standing my ground on everything I do, say and think for a bad attitude. My way of life has helped keep me alive and strong and I’m not going to change any aspect of my life for anyone regardless of the situation.
