The Fun part of ADHD is there's nothing unique to ADHD. Being overwhelmed with anxiety doesn't mean you have anxiety disorder. It's when you have frequent overwhelming anxiety and it's interfering with your life.

Having a tendency to put things down and lose them doesn't mean you have ADHD. Constantly having to find that screwdriver that was just in your hand and realizing that desk has been half complete for six months because you keep spending thirty seconds looking for it before getting distracted by other tasks? That's ADHD. Unless it's focus issues rooted in something else. Like anxiety or depression, which can cause ADHD like symptoms. But also ADHD can cause anxiety and depression, or be comorbid.

That said, you are here voluntarily on an ADHD community finding common ground with an ADHD meme. If you've wondered specifically about ADHD or more broadly felt there's something different about you've just never been able to put your finger on - this is your sign. My advice is to find a psychiatrist who really understand it, dig as deep as you can for hard evidence that you have or don't have it, and keep an open mind to alternative explanations. A diagnosis of "no you don't have ADHD" is also important information.

They're certainly common if you have ADHD, and ADHD is actually quite prevelent.
