The longest I've ever lived in one place is maybe 4 years - and everywhere else I've been less than 2 years. So I've done a shit ton of moving and I no longer mind it. I do love getting to re-decorate and re-think everything and really sort through all my junk and get rid of what I no longer need/want. The only thing I really, honestly hate is the physical labor. I am smooshy and weak.
My tip is to think through where everything is going to go. Pack by room as much as you can - and know that there will always be "misc crap" boxes. If you can make them "misc bathroom" or "misc bedroom" boxes, at the least, it will save you a lot of time when unpacking. If there's anything that's going to stay in boxes for some time - like books that are low priority - write everything on the box, and be thorough. That way when you're searching through boxes for something, you can ignore that box entirely. But it just takes way too much time to do that with all the other boxes, so that's only helpful on low priority stuff.
EDIT: Boro, my brother also went to Shepherd Pratt, for the same program, and it really helped him. He hated the group stuff just as much. Good on you for getting help for yourself. I hope you start feeling better soon!
