I know this situation well. She will not go to a counsellor, because she believes she is right and you and other non believers are wrong and influenced by evil. Put yourself in those shoes - would you listen to someone telling you to go to a counsellor to turn you against your righteous religion? (Rational person would not, but once beliefs get to this stage rationality has left the building). You will not change her mind. She will always view you with disdain. You have to accept this if you want to continue contact. Try to stay away from religious topics, but when inevitably she raises it you will need to brush it off and pretend she didn’t say hurtful things. This might be acceptable to you for the sake of maintaining a relationship. If it’s not, then the other option is to break contact. I know people mean well when saying try to empathise, but I have been in this situation and there is no solution that I know of. They will only come back if they decide it for themselves first. And very sadly, family is usually not enough of a motivator. The religious grip can be that strong.
