I am a 19 year old male college student. I feel that there is a strong possibility that I have ADHD. I am seeing a psychiatric nurse practitioner next month, but would like to know if the possibility is likely or not. My whole like I have always felt like my brain moves 10x faster than everyone else. I am always talking, thinking, or doing. In high school it was extremely difficult to concentrate in class, and now that I am in college it has only gotten worse. I did have speech issues when I was younger, as I was unable to pronounce certain sounds such as f . I also went through my elementary school report cards and found the teachers notes to comment on how they wished I would pay more attention in class. Now here is that last part that makes me think I might not have ADHD, I am a very good test-taker. During my first year of college, I missed a majority of my classes, but was able to teach myself the material THE NIGHT BEFORE the exam and somehow balance a 4.0 GPA. Opinions?
