I 150% get what you are saying. Especially with the physical exercise, people love to suggest that. As if you sit holed up in your house for fun. I got a pathological fracture with absolutely no trauma, I have osteoporosis and can feel the strain on my bones, I have a hip that spontaneously dislocates, and my range of motion is limited because my joints are not okay. How am I supposed to run or power walk or just go for walks often like that?
Are you able to go with someone if and when you start going on walks with your walker? Maybe try those high friction shoes with a grip too?
Yes, you definitely are tough. Life happened but you continued going on.
