Yeah, I think it could definitely help give them insight. Personally, I would give it to the therapist in session since it's rather long and I wouldn't expect them to spend the time to read it outside of session. I think I recall the one whom you will be having a second session with doesn't do between session contact, so it's possible he prefers to keep such things confined to the session - not sure that giving him 6.5 pages to read outside of session would be any different from expecting him to read a 6.5 page email.

But I do think you should share. If you think it will take up too much session time, perhaps it could be broken down into parts? Even if they did read it while you are out, it won't be very fresh in their minds unless they wait until it's a week or less before your appointment, imo.
