It's great that your daughter is playing soccer. That she's willing to give it a shot and see if it's her thing is what's important IMO.
I'm really glad to hear she has been doing better with the hair pulling. I like your idea about the meds. You can just watch and see. That's what I'm doing with my D (who won't wear hearing aids).
The steel you have is exactly how you get from day to day. That you get up and keep doing it is what makes you awesome.
