hey dreamstones--
gaaaaaaah - I have been in that same spot w/ my brothers...it can be especially hard after what seems like a serious move towards recovery, and the first time that happened I really got depressed and wrapped up in the drama...
Now that I've been through that cycle more than once I remember something I heard at a meeting - each episode of recovery plants a little more "bright side" in their minds, and gives them a few more tools to work with if they choose recovery again.
I also get much less excited by a glimpse of recovery. I try to maintain an even keel and keep my expectations and excitement in check!
It is sad though, and doubly sad about your dad and the cycle repeating itself. I hope you find some peace of mind soon.
Peace-
B
