There are times when admitting that you can’t physically do something you desperately want to do really hurts.
Just when you think you’ve come to terms with chronic pain and the physical limitations that go with it, something new crops up to remind you, yet again, that some doors close to you when you have a physical disability.
It’s not that other people tell you that you can’t do it. It’s knowing that trying will cause you physical pain and misery, and that you’ll end up regretting making the effort the minute you realise you can’t give it 100% and do the job like you used to. So you don’t take it on. You just internalise the disappointment and keep doing the things you can still do, without telling anyone how much it sucks for your own body to be the source of your misery.

Ouch! I find that my mind is younger than my body. There are times my mind says, “You can do this!” Then the body rebels and stubbornly refuses to cooperate.
As my doctor said, my biggest problem is that my brain thinks it is 25 and my spine thinks it’s 90.
My family saw that type of frustration up close and personal when mum was diagnosed with MS in her late 40s. So i’ll keep praying!
