No, I don't mind at all. My DD doesn't have ASD. We were very lucky to have been assigned an excellent therapist, who met with DD once a week. There was quite a bit of stuff that still weighed on her from primary school (bullying) and she needed to work through that. The therapist also met with us separately to support us, and help us through this. I thought this was unnecessary at first, but it turned out to be incredibly helpful. I know very well the intense worry you live with, every hour of every day, and sometimes you need to have someone asking how YOU are doing.
Music helped - she plays two instruments, and also listens to a lot of music. The school was really supportive and took the pressure off her by allowing her to drop a course, and allowed her the option (not always taken up) of coming in late one day a week so she could catch up on sleep (she was constantly tired). She was in Y8/Y9 though, so that might be more difficult in Y10.
Mostly though, it was time. With time, she got better. She began to have "good days", and those came a bit more frequently, until the good days happened more than the bad.
It's really alarming, as a parent, to see your child so distressed - you want to make it all better. You can't. You can only be there for her as a calm and loving mother, sometimes listening to DD, sometimes just silently holding her and stroking her hair (I did that a lot). Have faith that this will pass, and she'll come out on the other side.
And please feel free to DM me if I can offer any support.
