Sorry to hear the news, but I'm glad you discovered this issue before it became seriously fatal.
There IS life after
WoW (and AOC for that matter), but I find I have lots of "recovered" game time on my hands that has yet to find an outlet. In my case, I've taken advantage of the time to lose nearly 50 pounds since April and return to a regular program of "early to bed and early to rise" with my exercise program of choice in the mornings.
I miss the camaraderie and on-line time with friends, but I don't miss the "grind".
