Thank you for sharing. It sounds so difficult as it's as though each condition leads into the next @outlander .
You are a walking wonder.
And yes, orthotics are expensive. But one thing i remember my mum saying is that you need to look after your feet no matter how much it costs because your feet and the way you walk affect your hips and your spine. Even as kids, we didn't have much, but we always got new shoes every year. Not the pretty shiny shoes, but the ones specially made and fitted by professionals. So yeah, the orthotics help a lot and I'm willing for fork out for them, but the problem then lies with, what shoes do I wear? Unless they are sneaker or tailor made shoes, it's so hard to get the right shoe for orthotics, even if you get a size or 2 larger.
So as it stands, i have an amazing pair of sneakers that need to go out because they are so worn. However, they are one of the only pairs of shoes that do the trick with the orthotics... Oh well, we'll just keep trying.
As I said, my arthritis is minimal in the light of your health.
I just want to assure you that you really do have so many qualities to make you a great peer worker. Keep looking. There are over the phone roles too. You would be so amazing and understanding.
