End of an era

I just sent in my formal resignation letter. I can't help but feeling a little sad. It's the end of all opportunities in Regina, things to come and things that will never be. Is this what I want? Working for a private company where I get a raise and same benefits is hard to come by in Sask, that's an opportunity I can't pass up, but how much weight do I put on my personal life and professional career? What balance should they hold? I know I'll probably be able to come back to this position in the future, but everything is moving so fast. This week I've been told I will be missed greatly by many people for lots of different reasons, looked at condos, filled out a prequalification for a mortgage and packed up odds and ends. I can't help but feel uneasy and off about the whole thing. Am I just nervous, or am I intuitively telling myself something. I generally do have good instincts about stuff like this. I feel so on edge.
My boss asked me yesterday if I was sure I still wanted to go. He was totally joking but I was about to leap up and say just kidding, I'm staying, glad I fooled ya. But it got me thinking that even though I have sent in this letter I still have a choice. A choice I thought I already made. It's just nerves, go with it, you'll survive.
