Struggling with Depression and Chronic Illness

my depression and my mystery illnesses are really starting to be a pain in my ass. everytime I start to feel a bit better something happens. like. yesterday was the last day of my meds to help with some inflammation in my lower back and hips, was feeling great! was super excited that maybe now I'd have a chance to start getting back to my old life and back in working order (I run a small hobby farm with horses and I'm usually extremely active out in the barn). so what happened that could make this turn bad? I sat down on a stool. a stool we've had no issues with for years! I sat my ass down for it to completely shatter under me slamming me into the tile floor with a leg stuck under, you guess it, my lower back. I'm at square one all over again.. it's been the same story for the long 20 years I've had on this flying space rock :') everytime I come up with something to fix 'X' something always comes up and smashes it into the dirt.
