why at midnight though, maybe she meant to send it later or thought she needed to hear it asap depending on what may have been relayed to her about your daughter.

Coaches are more aware of mental health needs and taking precautions when needed. The fact that she reached out and your daughter is willing to talk is a good thing.

I would advise your daughter not go in expecting to be invited to the team as an injury replacement. Seems like the coach would have gone there initially if that was the case. If it happens, that’s fine but she needs to be prepared it to accept that the meeting is only took discuss her feelings and to check up on her.
