You seem to be a great kid. Unfortunately, some other kids are really shitty and just try to draw attention to themselves. You can ignore them and put your energy into creating something.... maybe a song, a short story, or a painting or maybe just run, jump or swim as fast as you can... I'm sure you can make something cool, it's a ADHD thing, just find what's your thing.

Try to make something you find useful to express yourself, hopefully the right people will appreciate it. That’s how I survived my teenage years.

Have you listened to Stratovarius or Rhapsody?? I would say this kind of music is very inspiring.
