Valerie, I understand where you are coming from. I would suggest that you look into insurance before you do anything. Does your family have a history of HD.
MIne does and like you i felt sure that I had it and was exhibiting symptoms.
I was tested and while i carry the gene i won't exhibit in my life time. I guess what I'm trying to say is don't give in too easily, stress can bring on similar symptoms. I don't mean this to sound like it is making light of your situation but having been there and read of other cases i can definitely say it is best to wait for the result. Try not to self diagnose.
In Australia the test is covered by our national health scheme we don't have to pay anything, are you sure this is not the case where you live. Have you discussed this with your doctor? Health insurance is definitely an issue, I'm not really sure what the answer is, except to say that if you have no family history of this disease then you sholdn't have a problem getting it. Goodluck, you've tapped into a great support system at this site.
