I want to speak to my Doctor, but how?

I would print out a few article online and bring them with you. I would tell the Dr that I had been feeling "down" (or however you would describe how you feel) and that you have been doing some reading. Some websites too have a little test you can take to determine of you are depressed. You could print out that little test for your Dr too. Just Google depression, and you will find a LOT of information.
