They probably haven't and those that have are faced with reality; it could be a long wait for therapy and a patient suffering or in their surgery constantly. So, they opt for the pills thinking they are doing the best for the patient and can end up getting it very wrong.
In my area before NICE it was a minimum 12 month wait to get help and pills were all their was. IAPT speeded up therapy but they also act as blockers to adequate therapies for those they can't help.

I would imagine you will find the same issue with all therapies if you look at success rates some CBT is considered a high one.
EMDR works in a very different way that is still not fully understood. It's always been sold more for trauma since it works at with memory processing, which CBT isn't aimed at.
There is a "Trauma Focused" version of CBT used for PTSD. Maybe that's worth a look too?
Schema Therapy has evidence emerging that it is able to treat Personality Disorders where CBT has failed.
They also use DBT to treat personality disorders because it takes CBT but adds further work to deal with accepting emotions.
Maybe some of those could be appropriate in dealing with more deep rooted issues?
