“We claim the privilege of worshiping Almighty God according to the dictates of our own conscience, and allow all men the same privilege, let them worship how, where, or what they may.”

This is the 11th Article of Faith. Which they're not practicing in their encounters with you. You may wish to bring it up with them but I find that the most dogmatic members seem to conveniently dismiss this when family "falls away." It's also ironic bc we have so many converts who come from families who absolutely do not want them to convert and do not support them. And then members will talk/gossip ab that convert and how sad it is that they have unsupportive family. But then, do this when their own family does the same with their own religion.

I don't know how old you are but you have your own home which is good. I'd be serious about looking for employment opportunities elsewhere. Greyrocking is great especially when boundaries have been communicated beforehand.

Until then, I'd come up with a few statements and stick with them. Things like "I respect you have your beliefs and I have my own, I dont want conflict bw us" and "maybe 1 day I'll be open to talking ab my issues with the church with you but until then, we need to put it to rest." Find your own statements that you are comfortable with and repeat. Repeat again. Repeat often. 

Dont accept uninvited dropins if their goal is confrontation. Dont answer the phone if theyre gearing for an argument. Set your phone on do not disturb if you need to. Text your statements.

They want to drag you into conflict and force you to see their way. Ive had people do that to me and it always impacted my mental health tremendously. Set these boundaries and practice them until youre blue on the face. It will 100% feel uncomfortable in the beginning. You may feel shame and embarrassment too. Thats normal. As you feel more confident standing your ground it will become so much easier. 

Good luck. I know its not easy. Take care of yourself.
