Fibro is a Bitch!

How do you tell yourself "it doesn't hurt"?  How do you convince yourself that your fibro pain isn't real?  Can this be done?
I have a super wonderful rheumatologist.  She's ranked one of if not THE best in North Carolina.  I've had a hard time coming to terms with being diagnosed with fibromyalga.  I was diagnosed in the summer of 2009.  Prior to that, I had lived with degenerative disc disease for nearly twenty years.
Looking back, I can see the tell tale signs of fibro through my life.  It wasn't until two years ago that it really started to affect me.  My back feels completely destroyed by the pain I feel.  I had twenty years to gradually get use to it deteriorating.  But the fibro came on like a beast.
My rheumatologist is very patient with me.  When my neck started hurting, she sent me in for an MRI.  Yes, I had a bulging disc.  Nice.  I filed that away with my other bulging disc, herniated disc and lesions on my spine.  The pain in my neck became too much to bear.  So did my lower back.  She sent me to a Spine Specialist.
Guess what?  Nothing in my spine warrants surgery.  Fibro strikes again.
My hands are always stiff.  It's a struggle to get out of bed or even to stand when I've been sitting to watch a t.v. show or drive my car.  She did blood tests to check everything out and make sure I didn't have a type of arthritis.  Guess what?  She said my innards are perfectly fine and no arthritis.  Fibro strikes again.
I'm tired easily, most days have zero energy, thinking about what needs to get done around the house and yard makes me tired.
That damn fibro strikes again!  And again and again!
So the last thing I want checked out are my knees.  I'll know later this month just how patient she is!

I want to tell myself "it doesn't hurt as bad as you think" and then I become angry.  Very angry.  I want to scream "Why me?  What did I do to deserve this!" but the better part of me says "put your big girl panties on and deal with it".  As I'm writing this, and it's why I'm writing this, my lower back hurts so damn bad I want to scream and cry.  I want to lay down on the couch and watch movies the rest of the night.  But I look out my window and see my car, with the doors open, my fishing stuff sitting in the driveway, my cats being nosey and jumping in and out of my car.  And I remember I had a good day yesterday.  I was tired, but not much pain.
So I must tell myself it doesn't hurt so bad.  Of course, I'm also waiting for my pain medication to kick in so I can go clean up the mess outside.

How do you tell yourself it doesn't hurt?  How do you make yourself get the hell up and get going?  How do you trust the pain you have is actual pain and not that damn fibro?  Yes yes, I know fibro is pain.  But it's a manipulative pain.  It manipulates you into thinking you have pain when you don't.  It's sending signals to your whole body that you hurt or your tired.  That damn fibro is a Bitch.  And if she (I say she because only a she could manipulate someone this way), would take human form, I'd kick her ass!
