Thank you.

I have spent the past two hours reading that last three years of my LJ and all I can say is, Thank You.  All of you have contributed so much to my life.  You have picked me up when I was down, posted links to zombies when I was miserable, given me sound advice when I desperately needed it, squeed at faerie goodness with me, encouraged me to be the person I've always wanted to be and so much more. 

I really couldn't ask for a better group of people to have in my life.  Every one of you is amazing in a way that makes the world better for you just being here.  Keep being awesome.
