What about number of books? No. 1 had only two, like on display on her windowsill - I did not know at the time but they were about EFT (Hold Me Tight was one of them). For some reason they disappeared halfway through my time with her.

No. 2 had a bookcase full, about trauma, anger management, EMDR, and abusive relationships.

No. 3 had a small shelf full, one of them also Hold Me Tight (this is when I connected it to EFT), the other two I remember are a medication guide and one called Motherless Daughters.

Maybe this should be a thread: what books does your therapist have in their office?
