Mopsey, He's down because he's had to start facing some of his issues. The therapist is working with him and may be helping him to figure things out. Depression is still at work here and you have to remember, you can't fix him.
I'm sure you'll be getting a tm sometime in the wee hours of morning. His pattern hasn't changed, so let him be for now. When he does contact you, then ask how he's doing. He's got a lot of work to do on himself before he grows up.
Please take care of yourself.
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.
