Beachlover, a sailor and beach lover here too!
I have been diagnosed with and treated for generalized anxiety disorder, severe recurrent clinical depression and PTSD since the early '90s. The tipping point was a bad car accident in which I was driving and my kids were in the car. I clearly had all of these conditions before the accident, but as a believing JW, they went untreated. I guess I was supposed to wait until the "New System" to recover from child sexual abuse and the fallout from the abuse from a psychotic Mom and an alcoholic father. The nightmares about torture in concentration camps, rape and torture in Malawi and the fiery execution at Armageddon of all of my non-believing family members were just icing on the cake.
I was in and out of therapy and on psych meds for two decades with little to no improvement. I now know that there is no way a therapist can help you without full disclosure. The elders had instructed me to not speak to my therapist about "spiritual matters". I should only speak to them about such things. I would say that I was a JW, but that religion was not up for discussion. I tied their hands behind their backs.
The organization, its policies, procedures, practices and teachings pushed me to the brink in early 2011. I walked away on July 3, 2011. I walked away a believer expecting to be destroyed by God.
A few months later I found jwfacts.com and read Crisis of Conscience and The God Delusion by Richard Dawkins. That is when my healing began. I have been off of all psych meds for over a year now. I still see my Buddhist Psychologist weekly. His approach is different than many traditional therapists, but it resonates with me.
This is what helped:
Dialectical Behavioral Therapy to help me learn communication and life skills I never learned in my 42 years as a JW. Health insurances in the U.S. usually pay for this evidence-based therapy.
Studying, practicing and now teaching evidence-based tai chi and qigong including sitting, standing and lying down meditation.
Mindfulness-based Stress Reduction
I am now training to be a (secular) Mindfulness Meditation teacher based on techniques of Minfulness-based Cognitive Therapy. You can read about the program here:

I meet weekly with my Insight Meditation Society meditation group. The teacher has a Zen Buddhism background which I find interesting and helpful. It's a great place to meet people who offer kind support.
I'm sorry it took me so long to get back to you. I wanted to take the time to give a well thought-out answer. For me working with the mind-body connection was key. Even when triggered, I haven't dissociated in years.
Wishing you peace and wellness,
