Thank you for your wonderful thoughts, and your prayers.
Here's one piece of advice I could give without playing Doctor, which I'm not. We all have our demons. A lot of us have been where your daughter is but with slightly different demons. A lot of us also beat those demons with the help of loved ones and the Big Guy. She is not alone.
I agree. Don't let her go back to school until she is mentally safe. She can go back and finish next year. I have three daughters and I adore them. Best, best to you, John.
