I know exactly how you feel.

It will get easier. Our twin boys went off to University last year, both in different directions ( Cardiff and Loughborough).Each week did get easier, I tried to keep my distance and let them have their independence. I threw myself into work and studying for a degree. This did help distract me, also the dog got walked more and I started running and gym classes.
When they did return for holidays ( christmas and Easter) I had not prepared myself for the same feelings coming back when they returned to campus.But these did recover a little quicker each time.
My husband and I even went to Florida on our own without the kids last year.I was so afraid it would be awful without the the boys. Although we did miss them and reminisssed a great deal, we actually were very liberated and were more like kids than ever at Disney. We were even family of the day at EPCOT on our first day ( we took this as a sign that it was right for us to go alone).
Someone said to me last year, to Just think what a wonderful gift it is to let our children go and how lucky they are. Its very true.
Also our young people are full of surprises. My one son who could not wait to leave home, visited us nearly every weekend towards the end of the first year.It was us who kept saying 'stay at Uni and be with your mates'.
This Sunday was a bad day for me. We have just been lucky enough to spend three weeks in Florida with the boys. When we returned from Gatwick last Thursday morning our DS drove straight to Cardiff. Then on Sunday our second DS returned to Uni, I was beside myself at the time. However, each day is better. My husband and I have spent some quality time and ticking along ok today.
We even picked up some holiday brochures.
All I can say is it will ease. I know it sounds a bit selfish, but I do think to myself that we have done a good job up to now and have enabled the boys to be lucky enough to go to university and have the opportunities that we never had.Be so very proud.
