How would xanax work for a new student?

So, I'm moving to a new school next year. I have some anxiety problems with meeting and talking to new people. Would xanax help me get over that initial hump(planning on using for 1-2 weeks)? If so, what dose should I take? Also, will I look like I'm on something? I don't want people to label me a druggie or anything. I would be getting the stuff through prescription, of course.
