Look outwards rather than inwards
Get out and talk to people (about anything)
Go somewhere new
Try new hobby/sport
After I had done a therapy session, I just made some key notes of things that needed reading/homework etc. then put my notes down for the rest of that day.
I planned to spend some homework sessions for the week ahead. Put a time limit on the sessions, then go do something completely different.
The day before the next therapy, write down things that need to be discussed with my therapist. Do not do anything more with my therapy notes on the morning of the therapy session. That way I found I was more relaxed when my therapy sesson started.
