I guess therapy is finally working for me, as I used to feel such horrible separation anxiety even to wait a week, and vacations/holidays were like being on a death watch. I don't know for sure what happened, or how, but now I seem to hold the T's presence inside me much better. I'm a little worried and irritated, but its not so unbearable as years past.
I do have a much better therapist than I ever did, and I trust her much more, so I'm sure that makes a difference, too.
