I'm in year 8 and I've struggled at school for the last 3years. I do not have dislexia or behavior?

I think that u should talk to your teachers parents I've had the same problem I'm in the 9 grade an have been struggling with school since 6 grade also I though that I wasn't any of that u probably have the same thing as me. I have add attention deficit disorder it's kind of like ADHD but you are not full of energy it's the opposite u have all the characteristics of ADHD but u have no energy.
