I bet you never had them care about you like this when you were going.
It will wear off eventually, with a few diehards maybe for a year. Then the obligatory visit just before the circuit overseer's visit so the body of elders can cross you off their list, "tried to contact, did not call back" or something like this. Unless the circuit overseer insists on making his own personal call, he will just take their word for it.
We still filter our calls, let them go to voice mall first to catch even those that don't list a name or a phone number. We didn't have any e-mail because we never gave ours out to jws. But those can be blocked too.
I wouldn't worry until you see some jws car sitting down the block from your house either during the day or at night that is there for some time. Take down the plate #, vehicle model (if you can figure it out) and color. If it happens enough to make you uneasy, call the police and just tell them there is a suspicious vehicle and give them the info. They will check on it and it might give the "stalker" a fright.
My family sent cards, letters, "care packages" of WT literature, sent them back unopened.
Just remember, it's your life, you can choose who you communicate with. You owe them no explanations, my motto, no pearls before swine.
Find new friends, at work, at school, neighbors, look up non-jw relatives, etc. And keep posting here, there isn't anything that someone on here hasn't experienced or dealt with.
Love, Blondie
