I got diagnosed with ADHD when I was 19 . Now looking back If only my parents talk to my doctor and had me put an order to get diagnosed when I was a young child I could have done better in school and probably done better and more bigger things in life. I still remember when I was a child teachers would be explaining a subject in my mind I'm like this teacher is speaking a whole different language. My mom would always yelled at me bitten asking why I can't be like my old sister or why I can't not be like such whatever child? Or why I wasn't in the smartest student at school. It has made a huge difference once I got diagnosed. For example I can get distracted by little things looking at a picture with a dog on it or someone can be talking to me and my mind would just wonder of. If you have ADHD you would know what I'm talking about. If you suspect you might have ADHD it is a good idea to get a diagnostic it makes a huge difference.
