I sometimes would plan my vacations around the time my T was going on vacation so I could be distracted with my own activities at that time. Anyone out of town you can visit for a week or so? Breaking up the "routine" of going to T helps me a little.

It's very hard. I wrote special journals and cards and mailed them to my T's office. My imagining her reading them when she "got back" helped. Maybe you can "schedule" a time or two when you'll e-mail her, tell her when to expect it and then it would be okay? You could think about what you would say and compose a little each day. My T once went away for nearly 3 months and I did a daily "lesson" I had learned that day, tried to get it into 1 sentence only, with the most important word or phrase bolded.
