Wow depression? Please help.?

Hey all, today I decided that after 2 years I had enough of wow. The game took my free time, I hated things use to love. I am still in shape etc etc but im just sad. WoW was so fun when I first started, the exploration, the feeling of the community. I now know about every aspect of the game played every cl 80+ and im just bored. Whats weird is I think of all the good memories I had with wow and I feel compelled to play, but when I do im just bored. I deleted my toons and im just depressed. Why was WoW so fun when I had just began playing it? I miss those days often and it saddens me so much. I hate cata and im just really sad any help would be great thanks.
