You know, I felt the same way, and it took me 10 years to get over it and finally see a doctor. That was 10 years wasted because I was afraid I wrong. Looking back on it, I don’t know what I was afraid of. Not going to the doctor resulted in the same thing as not getting the diagnosis!
ADHD isn’t a complicated condition to figure out, and someone who doesn’t have it is not likely to think they do to the point of actually seeing a doctor (yeah, it’s popular for people to say they’re ADHD merely because they multi-task a lot, but those people say it with pride and don’t seek out a doctor for it).
In other words, if you’re at the point of wanting medical help, it’s likely you need it.
