A belated welcome to the forum, Faith, this one from a town near Portland, Oregon --
I, too, was diagnosed in February -- but in 2002. My diagnosis came approximately five years after the first symptoms I can recall. Of course, at the time I did not recognise them as PD symptoms. Like you, I got along quite awhile without medication. Then as symptoms became noticeable and annoying, I started down the road of more and more meds over the years. The great thing about my case is that the meds plus exercise seem to have arrested the disease in its first stage. I know there are harder times ahead, but the longer I can delay them, the better. I am very glad I agreed to take Azilect (Rasagiline) when it came on the market, because I think it has been responsible (in part, at least) for slowing PD's progress.
It sounds to me as if you are doing very well at accepting this diagnosis. All of your reactions are perfectly normal. It is difficult to believe we have PD when we still feel like our old, familiar selves. Yet gradually we have enough experiences with symptoms to know it is true. Some people suffer severe depression around the time of diagnosis, another normal response. An optimist at heart, I escaped that, though I spent the first week in a serious and fearful mood. Immediately after diagnosis, I thought too much about the future; now I worry much less and just try to make good use of the present.
My best wishes to you!
