I felt sorry to hear from your daughter's condition. I wasn't sure why TSA had a problem with her. She couldn't stand and she can't move. Unfortunately, there is nothing can be done for now. You can get comment card from TSA. If you want to write the letter to your US Congress. Nobody who taking your own responsibilities. TSA will try to best everything they can. You are always welcome back to USA. You can fly to US anytime if you want.
