I need advice!

I’m not sure this is the right group to post in. If it doesn’t fit let me know where I can post instead.

Long story short my grandmother is a Jehovah’s Witness and I have nothing against that at all I’ll still listen to her and have an open mind about what she’s telling me and I applaud her for finding a religion she loves. However she was talking to me yesterday and trying to “convert me” to become a believer of her religion I politely declined and was respectful until she said well I hope you know your condemning your child and your soon to be baby (6 months pregnant) and because of your decision your killing your children and she also said I’m a horrible mother because of not following her religion. LET ME TELL YOU I was so LIVID I told her that that was a very inappropriate thing to say and very uncalled for them I excused myself to the bathroom letting her know I needed to cool down because I was extremely upset at the conversation. I cool down and come out of the bathroom and she goes “ I just want to save you do you can have eternal life with me instead of being selfish. I then told her to say her goodbyes to my daughter because I needed to leave. I have no clue what to do honestly I’m so mad and heartbroken.
