gneiss,
For me, I think I went into a rather protracted state of "mourning" the loss of wine. I felt much the same way you described. I did get out of the funk by reading, meditation tapes and keeping busy.
You have a lot going on so don't forget to take some "gneiss" time. And do try to stay connected with friends. Continue posting here. I find a lot of relief and support on SR.
Love,
Lenina
