Growing up with undiagnosed childhood ADHD, I (I was officially diagnosed at 22-23) felt continually lost in my surroundings.
When I was in class, and I would be asked to read from a book, I felt stupid and would ask someone else to take my turn.
And it was interesting to read about destructive behaviours. I had totally forgotten when I was around 12, I tried to self injure my knee.
I think I was doing it out of frustration to my parents. I felt I needed to talk to someone, not a friend, but an adult I could trust. But
it just wasn't an option at the time.
Now, as a disclosure, I have never tried to cut or injure myself since, It was a very brief period in my life.
I think I was frustrated at my parents, or school. I cannot remember for certain as that was almost 25 years ago.
Perhaps I couldn't express what I was really wanting to say because of lack of self worth, or awarenss of my body, I was 12!

But anyways, I remember getting quickly frustrated at everything. I had a hard time focusing on any type of homework. At the age of 12-13 I had just
gotten off of medication for seziures, so I am unsure if the ADHD had came about because of the medication. To this day, i have a hard time with
controlling my temper. Although I have started to not let certain things get to me.

Aside from the seizure medication, I have never been on any ADHD medication. I will never go on medication.
However, there are times I wish I was. But, I have learned to meditate. And although it is for a very short time frame (2-3 minutes, because lets
be honest, my mind will see something shiney and I will be distracted), it calms me down. I also work out 4 days out of the week.

However, for a teenager, and it were me and I was told to meditate, I'd be like NO!
On the flip side, If I were told to go to the mall and have fun with my friends, and just hang out and not be around parents, that would be perfect.
And if my parents were willing to pick me up after my time at the mall, that would have been even more awesome (especially for you)
...but I would have never tell them that.
Or, go to the local trampoline place to burn off energy, or roller skating arena where energy can be burnt off.

I know now that had I had the physical fitness portion added into my life I wouldn't have been a ball of stress.

Please ask me more questions as so many things I have forgotten...and if you ask the question I may be able to help you understand what your
daughter is going through. Is there a chance that you could give her a reset? Perhaps take her off medication? Just curious!
