I need some help please

I need ideas and suggestions. I am going to move my blog. I need it some place that will allow me to make some entries private. There is just so much going on that I need to be able to get out, but not allow the public to see I think.

Anyway, what I need is this. I need a username. You know, like in the address here it is tarnishedsiren. I don't want anything that labels me as only a mom, only a wife, or an infertility survivor. I want it to be about me. Right now, I don't have a single creative bone working, so I would really appreciate the input.

Thanks!
