Hi there,
I used to be in therapy with a wonderful man in Hammersmith area, called Geoffrey Sharman. At the time I got his number through the British Association for Behavioural and Cognitive Psychotherapies, since I had decided I wanted to do Cognitive Therapy, and his office was nearest to where I worked. Talk about good luck!!
I can't find his number on their site any longer, so he may have retired or stopped taking new patients...

If you decided that Cognitive Behavioural Therapy was right for you, you could use the Find a Therapist link on the left of the BABCP website, found here:
http://www.babcp.org.uk/The British Association for Counselling and Therapy is another good site for finding a therapist:
http://www.bacp.co.uk/Good luck and I hope someone can give you a recommendation for someone who's still practising! I hope you find someone you can really work with.
All the best,
Maitri
