I have no idea what you have, but I can tell it is causing you some concern. I could tell you not to worry, as if that could actually stop your worrying. ADD/ADHD is not fatal. I have had it all my life, and while it has led me down some interesting paths, I have not died from it.
The quick tests you take that say you could have ADD are like those artist adds on the matchbook covers: Just because you can draw a reasonable copy of the bird, doesn’t make you an artist. Just because you scored high(low) enough on the test, doesn’t mean you have ADD.
To find out if you do, you need to have a Psychiatrist or some other mental health professional, who specializes in diagnosis/treatment of ADD to perform a series of tests and interviews on you. This is to tell if you do have it. They look at your family as well. ADD is hereditary. They will look at your history. ADD is just a symptom of how your brain is constructed. They will try to determine how impairing it is. After all that you get the good/bad news.
I don’t know what the statistics are on diagnosis between girls and boys. Maybe someone else can answer that one.REPORT ABUSE
