Nice to meet you Alli. I am a mother of a 13 year old girl who was diagnosed in 1st grade and is currently on Adderall XR and she thinks she is the only one. Just know that there are adults/parents/teachers that are educated in what ADD/ADHD is and will help. Just ask!!
It isn't easy going thru these years in Jr & Sr High, just keep in mind from a parents point of view that we don't always understand and if you can explain and reach out to us, it will help us understand better how to help. My daughter doesn't want to understand this and would rather lash out and not speak so she can justify the 'my parents don't understand, nobody understands me' attitude. When she tries to 'pacify' us (her parents) she doesn't have a conversation to explain, she becomes over dramatic to where there is no point and when we try to bring reason & questions into the conversation to understand better she stomps off.
It is hard for everyone. You may have the diagnosis but you aren't the only one affected. Keep that in mind. Your whole family is affected, each in different ways. Your family is there for you and loves you no matter what. Remember this and lean on them for support and it will make the journey easier. Remember the friends you have around you as well.
