Hi Hismom. I hear you and it is all too familiar. We are with you all the way.
I was DXed at 35 and have had symptoms since age 23/24. I'm now 72 and holding.
Let us know how the MRI results turn out. The MRI alone may not be your DX tool. Often, early in the disease, your MRI may be normal, but other tests down the line will show the MS. I hope the MRI is your answer, though.
Hang in there..
