Oh Sarah, I am so sorry that you are having to deal with all of this right now!

I really wish that I could do something to help you and take your symptoms away but I know I can't unfortunately - just know that I care about you and am here for you whenever you need a shoulder to lean on!!
I really hope that your doctors can get to the bottom of your problems real soon. I for one, certainly understand your frustration and understand how awful it is to be undiagnosed. No, I don't think you are mad for wanting the MRI to show something - I remember feeling the same when I was undiagnosed, I absolutely didn't want anything to be wrong with me but I thought if the results came back abnormal, at least someone would care and believe me and would try and make me better!
Take care of yourself and know that we all care about you and will be here for you whenever you need anything!
