Go back tell them you we're having some issues but through pray you have had them resolved. Never admit to being on any apostate sites. After your back in start preparing your self for a new life out side of the cult. Then when your prepared better start fading away.
I totally agree with this.
If your story is real, then as an Elder, you should know what kind of mental-issue caused you to have a meltdown.
Tell your Elders about this stress, and that you need support.
Then, PLAN your fade and escape while building a life.
