It's great to hear about your experiences with CBT and hear from someone in the ~50% for whom CBT works. We certainly wouldn't bill it as a panacea for all conditions, as we've discussed in the comments section here, and it's wrong to see it as such, but for those who it works for it's an excellent tool. Also great to hear that so-called bibliotherapy has been of assistance to you.

As you allude to, while there are many academic papers showing the efficacy of CBT, DBT and ACT, in various forms of trial, some other forms of talk therapy are not backed by such a robust evidence base.
