I resisted getting professional help at your age, but it doesn't have to be a bad experience. Some doctors/therapists are better than others, and some meds work better than others for different people.

I personally refuse to go on Lithium, or any of the drugs with strong side effects, so my Pdoc put me on Lamictal, since it is relatively side-free for most people.

I have had bad therapists and doctors in the past and gave up, but I am glad I finally got a good one. Don't feel judged, you just have a disease and need treatment. Its normal.
