Whatever the outcome Fibro do not despair.
I have a friend who has neither PD nor Dementia. He had an horrific accident which left him in a coma for many months. He can watch a TV program tonight and watch the same thing again tomorrow with no memory of the previous viewing. He has adjusted to this and we now laugh about memory loss.
Being positive is hard, coming to terms with this sort of thing is scary. I will not pretend for one minute it is easy or without sadness.
I work on the principle tomorrow is important, next year isn't.......not till it gets here anyway.
This is the amusing side.......
My wife argued black was white with me this week in a supermarket that I had NOT bought some ham at a small bakery I had been in before the supermarket. Being in my usual confused mode, I thought, hells bells my memory is getting worse. So we got some from the supermarket.
When we got home there was the ham in the bakery bag. I looked at my my wife.......she put on her
'look at me aren't I cute face'
and we burst out laughing. It's no use getting annoyed. To hell with the world, they can adjust to me for a change, I've spent long enough adjusting to it.
I hope you get through the diagnosis OK. Whatever happens just be there for your Dad and tell him you'll get through it. Help is at hand and after adjustment it's not all bad.
