Do I have ADHD?? I collect more evidence every day!

Ok, I've been having ADHD symptoms for a long time, I can't concentrate well, I'm disconnected from the real world and everything feels like it's fake! I lose focus quickly, I get obsessed with things that I REALLY LIKE, like drawing or animation, and it's hard to concentrate at school!! I told my mom to take me to the doctor, that I need to get tested! If it comes out negative, then I won't see any justification for my weird actions ;-;
