What do you do when you are so nervous about something, you are crying contantly?

So I’m in Salt Lake City now. Tomorrow I’m heading to Vegas. Then I’m heading to Monterey, CA to begin a new job. I don’t have a place to live yet, I have never been there, and I don’t know anybody there. I know there is a big storm coming, but I’m really not at all concerned about that (me and weather, we sort of have an agreement).

So I find myself crying all the time, because I just can’t stand all these nerves. What can I do to put my mind at ease and relax? Or is it hopeless?
