I was surprised by my diagnosis of bipolar 1 disorder at first, but only because back in high school when a lot of my friends thought I had some form of bipolar and urged me to see my guidance counselor, I told my counselor about my concerns and she told me that I couldn't possibly be bipolar because I was "just a typical teenager"... and she assured me that "all teenagers have mood swings". I believed her, until an antidepressant I took triggered a severe mania& I got my bipolar diagnosis. (Which, looking back, so many things make much more sense.)
