Vickya, I suddenly became like that two years ago when I injured my back. It's still a problem and my whole life has changed.
I resist making plans as I'd rather just do stuff on a good day. I need a few days 'recovery' after long journeys or prolonged sitting. I go off for a lie down at any possible opportunity on family visits or days out (easier when outdoors in the summer) and I think twice about accepting invitations.
Things that I used to enjoy are sometimes just an ordeal now. I take the train to my daughter's place as a three hour car journey is just torture. Often, having got up at the crack of dawn and walked the dog, then travelled, they have an active adventure in mind for the day. I down the painkillers and try my best!
