I have GAD and then another disorder (trich) and someone mentioned ADHD to me the other day. At first I was like, no I don't have ADHD, but then I looked into it and realize that I actually do have a lot (a majority) of symptoms. Is this common? Can ADHD go undetected for 18 years or am I just psyching myself out? Maybe it's just my anxiety symptoms that are similar, but it's weird how much I realize that I've done a lot of "symptoms" for ADHD since like middle school and thought it was normal. Anyway I have no idea, so comments?
