If you are working with any competent professional they should be able to identify when you will need medical help right away.
There is a huge movement in north america to through drugs at everything. In Europe they take an entirely different approach on a lot of front and are seeing more success than us in those areas (ADD immediately comes to mind)
I'm not against medication, but I am against rushing to medication. I'd much rather someone try various forms of therapy first. CBT is just one of them, and happens to be working at a rate equal to or greater than prescription medication.
Edit: I wanted to thank you for the reply. Discussion surrounding the topic is critical to progression.
