Could i have ADHD (innattentive)?

innattentive meaning i do not have hyperactivity but i am pretty sure i have it. anyways...i have always know was different then they other kids. i learned slower. im disorganized. i get bored really easy, and i sometimes say things i shouldnt then regret them. i get confused over every little thing and have a really hard time comprehending things. i zone out so much. i forget what i was gonna say in mid sentence. even my friends say i zone out a lot. i have a short temper, and i always forget hw assignments. ive basically given up on school since its way to hard for me and no matter how i try i just get off topic and confused. my parents hve set up and appt for me to go to the doctors, i think i would do well with medications. how could i convince the doctor to give it to me if he starts to say no..? I SWARE IM NOT A DRUGGIE im a 14 year old female. thank you for your time
