I agree that it sounds like she has sensory processing issues. Those can accompany a number of disorders including ADHD, autism spectrum (not saying she is autistic) and in my experience as an OT, many of the people I treated with psychiatric illnesses that were severe had some degree of sensory issues. I personally have a lot of them, affecting clothing I wear, noise levels I can tolerate, my ability to relax and sleep because I'm always aware of everything (I sleep with a 22 lb weighted blanket which has brought much relief to all sensory issues for me and I actually spend a lot of my time under it awake or asleep because it is so calming). Sensory issues can increase behaviors if there is something that is becoming so overwhelming to the increased sensory system that it causes the need to get out of that situation no matter what. One of the ways that we tell I'm manic is that my therapist has 2 clocks in his office and when I am manic it annoys me greatly that they tick out of sync. He just re-arranged his office and the clock that has always sat beside the chair I sit in was moved so it will be interesting to see if I still am annoyed by it when it is far away from me). Aside from considering a weighted blanket though I'm not sure now is the time to do much with sensory stuf; I think it is a very secondary issue to everything else. But the weighted blanket might help. I had never in my life slept remotely nomrally until I got mine. I still don't sleep normally but I do sleep better with it and even had one made that is lighter that can go to the hospital or traveling with me because I really need it.
