You are not alone.
On our 1st trip to WDW 4 years ago, we flew home on a Saturday. I went to work on Monday and was miserable all day. Couldn't focus, just wanted to get out of there! So now, I never go back to work right away when I return. I always take a couple of extra days off to decompress and get through the post vacation blues.
Since we usually go during the school year, our DS8 will go back to school and on one of the days post trip, my DW and I will head to our local mall and just wander around the
Disney Store! We usually don't buy anything but at least in some small way we are still at Disney.
Start planning/talking about/booking your next vacation. On our trip to WDW 3 years back, we were staying at the WL and one the 1st day we noticed a flier in the room --- "Book now and SAVE!" HA! We just got here, not booking anything.... so fast forward to our last day and as we were getting our bags ready to leave the room and catch the shuttle back to the airport, DW was sitting on the bed, phone to her ear and the "Book now and SAVE!" flier in hand. 11 months later and we were back at the WL!! Just knowing that we would be back even before we left really helped us.
Not everyone can afford to do that for time/financial reasons or even for the fact that the next vacation will not be a Disney one. But whatever it will be, start getting excited about it now.
As our last few vacations have been to WDW and our upcoming one in Dec will also be, at least once a week, I find the Disney Vacation Planning DVD is playing in our house. It helps to keep us excited about what's to come
