Other posters have covered the essentials (great article, Cyn!)... but I just wanted to say congratulations on deciding to take this step. Seems like I read about so many people around here who are hesitant to get into counseling, when it's so clear that they would benefit from it... thus it really makes me happy to see someone so willing to sign up for it.
Good job, and good luck finding someone you can click with. Let us know how it goes.
