Not this year, but four years ago my DD went off to college and it was HARD on both of us!

She went to Central Michigan University, which is only about a 30-minute drive from where we live so she came home EVERY weekend but it was still really, really hard to let her go. We had always been close and she was basically a home-body. We both cried when we said good-bye in her dorm. She had a really hard time adjusting because her best friend from high school was supposed to be her roommate but at the last minute she couldn't go to college, so my DD had the room to herself. Her two suite-mates had boyfriends on campus so they immediately split and left her in the room alone, on her very first night, so that was hard for her to deal with. I remember many phone calls home. We had an arrangement with the phone company that she could call home (it was long distance) any time she wanted and it would be automatically charged to our home phone. It took her a couple of months to really "settle in" and begin to make friends but she still wanted to come home every weekend, and at Christmas she decided to move back home permanently. I didn't mind that at all.

She commuted the rest of the year, and the following year.
But, then she got married three years ago and I had to give her up all over again!

She lives just a quarter mile down the road so I still get to see her often though. I did adjust to her being gone a second time, and like another poster mentioned, you can clean and it will STAY that way!
My only advice for you is allow your DD to spread her wings, it will be hard for you, I know. Keep yourself busy, maybe get involved in some new things, make some new friends, take time for yourself to do fun things. But, keep in touch with your DD either by phone, e-mail, snail mail, etc. Make up care packages to send her, mail funny cards to her every now and then. Before you know it I bet you'll be adjusted.

Good luck!! ((hugs))
