Longgone: Is this just me?
No. It's not just you. What you experienced is called an indoctrinated phobia. It is the result of your experience in the JW cult.
Those phrases "new personality" and "serve" are triggers for us that are ex-JWs.
These induced phobias are difficult to overcome, but they can be by learning about them and by (ironically) engaging in mindfulness practices. The trick is to learn how to be mindful without getting pulled into another cult.
You can do this. Learn to trust yourself. You need no one else.
You're gonna be okay.
