Joanella, Don't be afraid to take .5mg it is a normal dose, actually on the smaller side. I was actually taking 1 mg at a point. But, after you take it go relax, try to stay focus on other things OTHER THAN YOUR HEALTH, and it will start calming you. You are so wound tight, stop googling, stop watching health shows, stop reading books whatever you are doing about health related stop. It is a vicious cycle this hypochondria, you cannot research on your own, it will be a never ending battle for you. Go to your neuro on Friday, you will get great news, at that point take that information and run with it, and stay focused on what your neuro tells you and nothing else. I am 100 percent confident you will get the all clear and great news.I have been at this for 2 years, it will never get better until you stop the vicious cycle. The only thought that should be in your head is I AM HEALTHY.Terri
