1 trip to your Doctor, telling him that you have really bad nerves. You can't eat, you can't sleep, everything and anything is on your mind. Your thoughts race from person to person when you're out in public. Doctor, I believe I need something for my nerves and I was told about Xanax. Perhaps you could subscribe a small dosage to me to calm me down and make me functionable. I would really appreciate it.
He'll write you out a prescription, go to your pharmacy and get them filled. Go home, pop a chill pill and experience a world of semi-relaxation! Good luck.
