You sound pretty enthusiastic and optimistic - and one great thing about PTSD is that it can be gotten over fairly quickly (not always - so those struggling with it a long time don't think that I'm being dismissive - I've had it for decades myself).

PTSD is more like a brain injury than an actual disease, but yeah, an injury can mean anything from "like a broken arm" to "like a spinal cord compression" - so just because there are some of us who have been stuck long term does not mean that you might not be over it in 3 months with EMDR.

Especially since, if I understand you correctly, you were already in treatment for Borderline, which is also curable, you might be just fine in 3 months.
