The best way to handle it is:
Don't answer your phone. Screen your calls and texts.
Don't answer the door.
If you bump into anyone in public, tell them you are doing GREAT/never better. Make sure you smile. Remember, you are still the same wonderful person you were before you left (minus the cult). If they push it, just tell them you appreciate their concern and if you need them they can give you their # and you will call them. If they continue to push it and ask intrusive questions, just tell them you do not feel the need to discuss that with them. If your rude, like me, just tell em it's none of their business.
Look like you are ecstatic and it will drive them crazy. JW's are programmed to interfere in your life and when you look down and depressed it's "because you left Jehovah."
You owe these people NOTHING!
