My dad didn't speak to me for about a year during the height of COVID because I went off on masks, jabs, etc. during a blowup and because I wasn't jabbed. Eventually the propaganda wore off and he started realizing that life is too short for such division, as well as realizing what he was informed about regarding the vaccines was consistently changing in the opposite direction. I'm just saying, it might take some time. Trump doing good things for the country might turn her around at some point. Just keep her in your heart and your prayers and ask God to soothe her pain and clear her mind.
