It's very hard to diagnose fibro with only those symptoms.. like it was suggested above, consulting a doctor is your best bet.
Your wife trying to explain your condition with something else might be a hint that she doesn't fully understand what you're going thru.
In my family it was my godfather who was diagnosed with fibro.. even tho we were supportive of him, I understand your need to find someone else who's exactly in the same place as you, because it's the same with him.
And like has been said, you gotta take other folks input with a filter, just...
Hi there, my name's Dave,
I've had a familiar diagnosed with fibro, I'd like to know more about this..
I'm usualy a positive and upbeat person so maybe we can also talk about other subjects that make us smile. :P
