Isn't it amazing at the contrast? I imagine you still feel like you can still do those things and yet can't in reality. It's such a shock.
A few months ago I was with some very athletic friends and we were goofing off and suddenly a pole climbing competition broke out. I knew I'd have no problem getting to the top quickly. Instead, I was barely off the ground and every ounce of my energy was expended in about two seconds. I was devastated and that's when I realized something was wrong and eventually discovered AF. I'm still in disbelief and can't wait to get my energy back.
Yes, I purchased a saliva test from my doctor, but since I'm female, apparently I can't just jump in but have to wait for specific days. I'd be curious to hear what your results indicate!
