Pain condition complex medical diagnonsenses YET MY UNDOING IS FROM MY OWN HEAD

I suffer* from a few medical conditions and the greatest hit is my mental health -they are all true but I am close to several people telling me they are not and I am very much struggling to keep my head above the parapet.

*even using the word suffer makes me cringe...ok I can't walk unaided and I'm sore and I don't have a day without pain...but there are people in this world with NOTHING. People starving to death. People so mistreated I could never properly contemplate it. People abandoned LITERALLY at the side of a road, left to die because they have become too difficult for that family to care for...
