They have been at my door about every other day.
How annoying! My suggestion is to try and ignore them and hopefully they will stop their harrassment. I haven't had a call in years. Sooner or later they forget about you and move on to someone else.
As far as my parents go, there is always that little nagging in my head that tells me I am disappointing them.
Your parents are enslaved to a cult. You will be a disappointment to them and there is nothing you can do about it. The alternative is to remain a JW and you've already worked out that you don't want to do that. It will get easier over time.
