I’m so sorry that your parents have disowned you.
Did something happen?
Or as @Travelinglady asked, could they have impaired cognitive function (dementia?) or personality changes?
Anyway, regardless I just wanted to say that I’m so sorry you’re experiencing this.
I don’t have any experience with this so I don’t really have any advice, just warm wishes to you both, @bpforever1 and @NatalieJastrow
