It sounds to me like you're burnt out. Too much mmorpg, not good for you, time to take a break

. Same thing happened to me a few months ago.
Solution, go play some single player games for awhile. A few I played were 'Overlord', 'Oblivion' and the amazing 'Thief: Deadly Shadows' (one of the best games I've ever played).
When I finished that lot, I was ready to face a mmorpg again. At the moment I'm playing 'Rappelz' (it's not bad. Not great, but not bad) and I've been trying out 'Perfect World' (this shows a lot of promise, but the grind may kill it for me, I felt the grind start to bite at level 2. Ouch! >

).
Someone mentioned 'Guild Wars' and I'd like to recommend that one too. Personally, I don't play it, I'm more of a solo player and in Guild Wars there's too much reliance on partying. But my Mother and Sister love it!
If you can find a good guild and a few friends, then you'll have a blast. If you prefer to solo, then try Rappelz. I'm playing an Asura Shadow Hunter and I'm not having any trouble at all.
Unfortunately, all of these free mmorpg's seem to be churned out by the same old machine. The only ones I've found that have any type of end-game content and offer a bit more to do other than grind, are Rappelz, Perfect World and Silkroad (to an extent).
Anyway, I wish you luck.
