That sounds like a good idea but, yeah. I can't just pick any hobby it has to be something I like and the last six years of my life have been invested in this game and all of my friends are there. I feel important in my guild. I feel loved by my guild. I know it may be over the internet but it's real to me.
Best tip I can give is find something else that you feel is rewarding and fun to do, quitting wow and then sitting there staring at the wall is going to be extremely hard, so I dunno try find a new hobby if you feel WoW is not for you anymore.
