My preferred method of relaxation would always be a general anaesthetic
I thought "CBT" as it is offered on the NHS was only suitable for mild to moderate cases. Anything more long term-apart from psychotherapy-would of necessity have to be privately funded by the individual as it's not really practical financially for people to have limitless sessions with an NHS practitioner. Just imagine the waiting lists! I had to wait over 2 years for my CBT 10 years ago and I think I got 16 sessions which barely scratched the surface. I was offered psychotherapy but turned it down as I couldn't commit to long term therapy as I'm a carer and I was very frightened as to how it would affect my day-to-day caring for my daughter.
I think that there's too much fancy terminology used today for mental health services when a lot of it is just common sense. Also far too many "therapists" jumping on the bandwagon taking advantage of vulnerable people.
