I'm glad you found PC to be able to put a voice to your sadness and frustration. When you were thinking rationally (?) you felt the best thing would be for her to go to her dad's. Perhaps you are second guessing that decision, but it might not be a good idea to try and change it back right now?

IDK.

What you can do is (as others suggested) is write to her, and ask her about emailing too. Maintain the best you can, because she is still impressionable and everything you say and do now will play an important part of her future judgments. She's growing up, and needs you to be "there" where you are, for her. Don't give her reason to feed the (wrong?) impression she has right now... things can and probably will change.

Don't force the issue, but take this time away from her to show her long distance love. She can't be in both places at the same time.

I'm glad that you have a T, and one who believes in you. I think you must be strong. Instead of giving up, you kept looking to help and improve and found PC!

Depression is a tough dx. Do your best for the day, each day and things will change. TC
