Hi Jane, sorry to hear about the diagnosis. Sometimes just hearing it said aloud can make it all so real. I remember when mine came. I had an MRI (just to be safe the doc said) because of headaches, dizziness, and very very mild optic neuritis.
It came back with 9 lesions. I got the call only 1 hour after I got home from the MRI and my GP called with the "I have some bad news. You have MS." I was in such shock I fainted. The doctor was leaving the next day to go on vacation so I was just dealing with strangers as I got admitted to the hospital for IV steroids for the optic neuritis.
And then of course the steroids mess with your moods and I was bawling like a baby for days. It will be 5 years next month. I've been lucky with no relapses. I hope you are too.
