Khaleesi
Remember this important fact :
"The only power they have over you is the power you give them"
They have NO power OR authority over you unless YOU give it to them
Do not fall into that trap.
It is as you said your worship to God is between you and him alone nobody else , when they try to badger you say , It`s between me and my God and nobody else , thank you for your concern , and say nothing else to them , do not engage in conversation as they will try to trap you in your words.
Take care , I wish you all the best
