Could it be Fibromyalgia

For awhile now, I have been so exhausted I can barely function. I went to see my PC 2 weeks ago and almost fell asleep waiting for her. I also feel achy all the time, the same type of achyness as the Flu. I also have been dealing with issues like memory loss, spasms, feeling dizzy at times, losing control of my bladder while sleeping and not realizing until I wake up in the morning. I saw a Neuro about the memory loss etc, she ordered a bunch of tests and everything came back as "We can't find a functional reason as to why all this is happening to you." I saw a second Neuro at a Brain and Stroke Center, and she said the exact same thing. The exhaustion and achyness was so bad a few days ago, I couldnt even get off the couch to make dinner for a few hours. I emptied and refilled my dishwasher and I had to sit down because i was so tired and achy. I get so achy that it hurts to lay down to rest, so I have to take Tylenol to make the achyness lower enough for me to sleep. My PC ordered a bunch of blood work and i see her in a few weeks. We did discuss both Chronic Fatigue and Fibromyalgia, and she is considering (for lack of a better term) that it's Fibro. Anyone have any thoughts? And if it turns out to be Fibro, does anyone have advice as to how to tell parents who think you're making it up? Please don't judge me. thanks
