Well, at least she finally realized that her choices have had consequences. Has S10 gone to see someone (I know that you are not in love with ICs). You might suggest that she and S also line up a family C at this point, seeing that so much is happening in your family. Maybe she will have a little light shined on herself...
But it could help with your S. I hate to read the thing about the screaming - I don't believe that is necessary with any student athlete, let alone those so young. It sounds like there is a league - can you get in touch with someone at that level, so it doesn't get back to the specific coach? It might be a good idea to have someone at the league level go and observe how the coach acts....
