I always try to be honest with my pdoc and T (when I used to have a T). Like others have said, whats the point in going if your not honest. They need all the information to make the best decisions for your health. Luckily I have a great relationship with my pdoc and used to have a great relationship with my T before I moved cities (I still drive to the next city to see my pdoc but its too far for weekly T!) Often I don't realise that Im depressed or hypomanic but by answering his questions it becomes clear - so I am lucky that he always seems to be able to figure things out even if I think I'm fine.
