I don’t know if this is normal or not. My psychiatrist waited for several visits before he even brought up the labels…and then he said he thought I was struggling with depression, anxiety and PTSD. He did not even say I had the disorders—just that I was struggling with some of the symptoms. It does sound odd that a pdoc could diagnosis you in 20 mins—that’s not much time. If a pdoc tried to diagnosis me in 20 mins, I’d get a second opinion.
