I've had years of therapy and thought I knew what my 'problems' were. But 22 years of chronic pain (so-called fibromyalgia) led me to Sarno's book and then to this site. The journaling (which I REALLY didn't want to do) has been amazingly helpful. I start writing about something and I 'think' I know where its heading. But suddenly my writing/emotions/subconscious zooms off and several pages later I realise that what I thought was the problem in a situation - wasn't - it was something else totally. Hidden from me - by my unconscious! It has been invaluable. I found writing with my right hand (I'm a lefty) was very powerful - I felt like a tiny child learning to write again.
Also the meditation and mindfulness. I have meditated, alone and in groups for many years - but the TMS/ Freedom from Fibromyalgia meditations have been SO much more use to me. I now use mindfulness - and body awareness several times a day - and every night to go to sleep - without anxiety, without palpitations, without insomnia.
It is brilliant. So I would say - DO the journaling - see what happens, give it the full 42 days of the programme - and then look back and see if you think it has helped.
Either way - don't feel 'guilty' - it is up to you - you get out when you put in....
