Thought that I would respond to this, since its my biggest hurdle
I am one of those people that when its a good day, I'd run like heck, and try and get as much done as I could, then I would drop and wouldn't be able to do anything for days, sometimes weeks.
I did get myself into trouble, because I just kept pushing until I was so weak.
I learned that its best not to do that, rest when you have to, and pushing is not a good thing.
Now everything in moderation. Any heavy stuff my husband does, ie vacuming is one thing.
When I cook, I use a serrated knife for cutting veggies and stuff, the hardest first, like carrots. With the serrated knife you don't have to push.
And then my husband helps again. I don't know what I would do with out him.
I try and sit when I can, like folding laundry. Always looking for ways to conserve energy.
I guess that you just learn as you go, everyday is different.
Its really is hard on your mind, to get your brain around not being able to do the stuff that you use to take for granted.
I still have problems with that
Hope this helped some, take care, Patricia
