I think you did the proper thing by emailing and acknowledgement back to him. I just wanted you to step back a little before you responded, i.e., not a knee jerk reaction at that time.

You did just fine. It was a very kind response. Nice job!

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.
