Other habits, I always sleep with the plushie he gave me, I literally take it everywhere with me, even away on my volunteering trips although I try to make sure people don't see it as it makes me feel a bit silly. I also find, that since my last stay in the U.S where we got to sleep in the same bed all the time, I have to sleep with something like a hoodie or similar bundled up against my back, to make it feel like there's another body against my back. It's silly, but it helps.
