Am I a little crazy or is this normal?

[CleanUpMan]

First off, if this is in the wrong section I apologize.

I have only been playing poker seriously for about 3 years now. About 6 months ago I started thinking about poker non-stop. If I'm not playing, I'm watching it on T.V. If I'm not watching, I'm reading books. I constantly try to talk to my friends or wife about poker and they could care less. Lately, I even find myself having a hard time falling asleep because I keep replaying different hands and situations over and over again in my head. Many of my friends and family think I'm nuts but over the last 6 months my game has improved drastically. Is this the kind of mind set it takes to win or am I just crazy? Please tell me there's others like me.
