First of all, it's good that you made the decision to be proactive and see a doctor. That's a big step for most people. You're not going to unravel your entire life's story in one session, so don't get too anxious about it. The doc is going to ask you a lot of questions since they are meeting you for the first time, so just be honest and answer them. Sometimes they ask you questions about things you haven't even thought about before that makes you look at things in a different way. And don't be afraid to ask questions of your own. It takes a while for you to get to know each other and you'll be more comfortable after seeing them a few times. I doubt that they would prescribe any medications after seeing you only once, but it is possible. Don't be afraid to ask questions about medications, or research them yourself before taking them, if that makes you more comfortable with it. You don't have to do anything you are really not ok with. But remember that you are getting the opinion of a professional, and there's no need to be afraid. Good luck!
