I think I would be a bit hurt if my T used that exact phrasing, but I would also understand that she's expressing frustration that she couldn't help and a genuine desire to want to help. If she didn't want to really help, she wouldn't have said anything at all.

I am sorry you are struggling so much. I echo Rainbow's wish that your T would be able to find alternate methods to help you express yourself when you can't speak. Please hang in there!
