Just one more thought - it may be worth speaking to your GP about this, to draw their attention to your therapist's recommendation for schema therapy and let them know that you would like to do this therapy. So in case it becomes available in the NHS, or if in future there is the opportunity of a trial or something like that, your GP would be able to put you forward.

I understand what you mean about the book being upsetting. It's quite a powerful therapy and I think it can be upsetting for that reason. So I think it's so important to go at your own pace and to be supported.

I wish you all the best.
