First off, there's a reason they call it "prescription medication", and that's the fact YOU NEED A PRESCRIPTION TO OBTAIN IT! D'oh!
WHAT is driving all the anxiety? Why the hell are you so wound up all the time? What the is causing you to be depressed? You need to answer these questions for yourself honestly.
Let me give you some words of advice I have lived by for many years. If you heed them your life will become immeasurably better and happier. "It is useless to worry about that which you cannot change, and, if you can change it, why would you worry about it?"
EDIT @ Sariah: Sariah, doesn't all of that stuff you're obsessing over fall under the advice I gave you in my initial response about worrying? Of course it does. Look, try using the "Deathbed Test". In other words, when you're in the last days or hours of your life, lying in a hospital bed, what are the things you will be thinking about? If the crap you're obsessing about NOW doesn't fall into that list of things you'll be thinking about THEN you are wasting your life on this mess! Life is too short to invest a single moment of it "pre-planning" scenarios that you can do NOTHING about or prevent in any way.
