hi im 15 and i think i have adhd, i have really bad grades, cant concentrate on my studies, theyre really really boring and i sometimes i just want to run away when i am forced to study. once i decide something in one day (like a schedule to study or something) i completely forget about it, or force myself not to think about it , i sometimes get hyper focused on somethin (like video games) once i returned from school (and was really really hungry) but got stuck to the computer, but only got up when i started get dizzy and all. whenever someone opens topic of my interest (like social studies) i get so over attentioned or something , i answer to things without the question is completed, and fidget. and i make wierd noises with my throat whenever im talking about a really intersting topic and brain seems to have accelated to 5000x. i am really forgetfull and irresponsible, iforget my lunch almost everyday , if i went to the market to buy milk and eggs , i end up buying eggs and forgetting the milk. i cant talk to people except my family, icant read long passages, i talk before i think. and my mother tells me whenever she took me to her office (in which i had to sit for hours quietly, i used to have tantrums so that she wont take me there) And i cant sleep at night without dreaming about my life, or how it would have been, and various other things, video games tv series and stuff ..for nearly an hour.
do i really have adhd or is this normal?????
