I hope you find the book helpful, I certainly did.
So easy to understand and the Mindfulness not too textbook if you know what I mean.
I wouldn't be able to do group therapy either or travel long distance.
I did seek my own private therapist and if you search around you can find one that suits your needs, some even come to you.
The NHS also don't tell you that you only get 6 sessions, then you have to pay. I had 3 years with therapists and it still didn't cure me, but was good to offload.
