Anxiety/Depression tend to go hand-in-hand with ADD/ADHD. Although A & D tend to be in flux while ADD/ADHD is constant(At least that's how it is for me, I was diagnosed when I was about 12 and been on and off medication since). I'm currently on 3 medications for all 3 disorders. However it's probably something I would not recommend to put that many medications on as some one as young as your daughter, especially since she's right at puberty age. I'm currently 23 and it took quite a bit of time for my body to outgrow the side effects for the combination I'm using.

Going through school with this disorder can be challenging. Not just with the focusing/concentration, but not many people clearly understand it and tend to mislabel or misjudge it. Sadly, there are some people who just put it off as laziness... which is nothing further from the truth.

I'll stop myself from rambling too much... Is there anything else you want to know?
