I have complicated chronic pain too and had a therapist for a long time who mostly did CBT, though there were no worksheets, I'm happy to say. I did find her helpful at the beginning, mostly because she made gave some good practical advice and was useful, as others have said, as someone to talk to who was not my husband or friends. And we did guided meditations which I found helpful at the time. However in later sessions I found my jaw dropping mentally at some of her suggestions, including basically ignoring my past trauma (physical and verbal abuse as a child) and the affect it had on how I react to certain situations today.
I'm lucky not to be under the NHS and am now with a therapist at my pain clinic who uses a variety of techniques and has experience in trauma. I'm finding her a much better fit,
I do empathise about the difficulties of travel and sitting in a plastic chair - I have trouble sitting too (back and hip issues, and I can't walk much either as I need an ankle replacement) and I feel it's generally a misunderstood problem.
My DH did ACT for a particular issue and it was very successful, so I think these kind of therapies can work in certain situations. It's a shame there is not a system with an assessment session to determine what kind of therapy might be useful, rather than pushing CBT on people for whom it is unlikely to work.
I won't send
as you said you don't like them, so unmumsnetty hugs,
and
for you.
