It's got nothing to do with the web. Put bluntly, it means your brain is wired slightly differently. This isn't a 'bad' thing but it means that you may struggle with things that others find simple. But this can be mitigated greatly with proper counselling. I'm sure you will find there are advantages to having ADHD but it's crucial to understand exactly what it is and how it affects you in many different ways. Also having ADHD in no way implies that you are 'damaged' or 'special'. Just think of it like it's an ingrown toenail. Good luck.
Edit: i would also add that learning proper coping mechanisms is at least as important as taking medications in that the pills would have very little effect unless taken with the correct mindset.
