I'm really confused about this right now. I'm diagnosed with ADD, GAD, and depression, and my therapist said she hasn't ruled out bipolar disorder. I've been doing some reading and some of the symptoms I've been associating with ADD also sound like mania? which, now that I think about it, is also odd, because my ADD is overwhelmingly inattentive type. there are other things too that sound more like bipolar than ADD. it's hard for me to tell what are abnormal degrees of behavior/experience and what are normal ones, because most of the people I'm close to exhibit a variety of disorders, and I've spent a lot of my life convincing myself that I'm completely ok (to my detriment).
