The only thing that helps is having a placeholder or another cruise booked. The knowledge that it's not over forever just for now is how I cope. Reality is just not as joyful. I also tell myself that without the day to day I couldn't afford the occasional
DCL trip. Alas.
The last cruise we did (not DCL tho), blues didn't kick in until a couple days later when I started realizing people just weren't as into what I did on my vacation as I was. To this day I still catch myself saying, "when I was in/on/at..." So I participate on these boards with like minded people to live vicariously or relive my moments.
I do have to say going on another line is great but even then I find myself missing the Disney magics.
