My GP was the one who prescribed me Xanax. She could see that I was a NERVOUS WRECK and needed it. I, too, was afraid to take it, but I did, and it was scary, but after a few moments, I felt ... normal. For a time, of course, and then it wore off—but, it was a great way to realize that what I was experiencing was anxiety-related, and not something physically, dangerously wrong.
My advice—take it—responsibly of course; not more than you're prescribed—and when you take it the first time, take it with someone else in the room.
