Last day

I was surprisingly emotional saying goodbye after work today. I didn't think for a second I'd be affected by leaving my current job and the people I've come to know over the past 6 months. Apparently I failed to realize how much of a replacement family my co-workers had become. They're all I've known for 6 months.. and the closest thing I have to friends or family here. Seeing them day after day for half a year, you become attached. And now I feel like I have to start all over. I was only just feeling settled here, and now everything's been flipped on its head and I'm back at ground zero.
