If a healthy person suddenly felt my pain, nausea, and exhaustion they would call out sick and maybe even go to the hospital. But just like everyone else with chronic illness, the longer it goes on the more life is intolerant of your perpetual health issues and all you can do is deal. If you became disabled tomorrow you either have to deal or die.
How one copes varies, but one thing is for sure, unless it happens to you, (and for real I don't wish this on anyone) you cannot possible understand what it's like. Please respect that and stop acting like you're our doctor when you find out our conditions. We've heard it all and done it all.
