I'm sorry to hear that your daughter had an accident last night with a knife. I'm sure she was very upset by the accident.
I hope that you and your daughter are feeling much better soon. Glad to hear that you are getting a little bit more sleep in at night.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
