It's a huge element to being a JW.
I remember consciously remember the relief of letting go of the perpetual, inescapable guilt that is unhealthy.
Those hormones responses and and sensitivities remain even when we leave, as a JW that guilt was purposefully cultivates as it was a strong motivator for WT's wants.
With time it dissipates but even now I will have moments where I have to fight the feeling of inexplicable guilt and it is, in my opinion, a remenant of the JW past.
btw; it gets so much better/easier as time passes and the letting go of perpetual guilt is one of the significant & rewarding benefits of leaving the JW cult.
