Did an NHS doc advise you on CBT? One psychiatrist told me it's just a fancy term for positive thinking. There's no way anything like that could help me, because i'd just be too aware that it's poisons that are screwing up my thoughts, and the thought of sitting in front of a therapist who knows nothing about what most of us know on this forum, disturbs me. It depends what your problems and situation is, but ANY therapy made me feel more suicidal, because they just had no clue how i am affected, or most importantly, WHY.
