Is anyone else tired of wondering???

I was diagnosed a few years ago with fibro after years of unexplained symptoms...tension knots in my neck/back/shoulders, burning tongue, tired, numbness, ect. I take medication, but I just always feel like maybe it is all in my head! It is so frustrating! I work full time. When I am at home I just want to sit! I exercise every morning. I am 51, but I don't know, it is such a pain in the a_ _ !! I do not wish to be diagnosed with anything else, but I do wish their was without any doubt that I have fibro, and it is not in my head! Just venting I guess, sorry but thanks for reading...
