I think one important thing to do is to accept that you don't drink alcohol, ever. Allow yourself to sit with those feelings. When I did that, my mind began to come up with healthy ways to deal with things.
For Christmas, since you're in early recovery, I'd suggest staying away from alcohol whenever possible. Maybe you could come up with things to do that don't involve drinking? You can make new traditions and memories for Christmas and New Years with no alcohol.
