Who's to say? ADHD and anxiety are so similar, think about someone who is afraid to drive for example because they get anxious when they drive. That same person might be able to drive at night or when there's no traffic. Why? Because the sun isn't shining in your face, the 19 year old in his Audi isn't blaring his music next to you, theres not beeping, yelling, anything. Your brain isn't anxious because it's not trying to process 25 different things at once. I mean really think about how similar they are. Maybe you can't walk into Walmart or a big store because there's too much too look at, too many objects, noises, people shuffling. I think this really needs to be looked at further by psychiatrists. If your brain is trying to process all this what's it gonna do? It's gonna go frigin haywire and panic.
