I did... I have been told by those who know me that I seem to have ADD or ADHD, but I have never been diagnosed with it by a professional.

I guess it was because most professionals assume that low ability to focus and lack of awareness of the detail are part of my other issues rather than an attention deficit.
I know that people with depression, anxiety or basically most of the mental health issues can experience such symptoms.

I've never gotten to talking more in depth about it with a professional, because since it has been a part of me my whole life, I thought my current issues such as depression were more appropriate to discuss.
