I can’t speak for others in this situation, however, my daughter is bipolar and finally started living the Catholic faith. Then she read a website about Fatima and I think it might have been by Catholics not in communion with the Pope.
At the same time she met a Facebook friend who is not baptized, was not, nor is really Christian and she started mixing up Fatima and the last days, plus conspiracy theories.
I feel she is now delusional as she feels God speaks to her and the BVM spoke to her and told her she would tell her when to flee. I have tried to reason with her, however her illness has taken over. I am glad she has a strong belief now, but she thinks God tells her everything and then she goes to the web and whatever He supposedly said is confirmed by a conspiracy website which brings into it the fundamentalist religions view of the last days.
My daughter is now afraid that she has done something wrong and will go to hell and believes that we are soon to be invaded by terrorists from different countries and it goes on and on.
I believe that people who are either emotionally unstable, have a mental disability or are ignorant buy into these beliefs.
Of course the world is in bad shape, however the only thing a Christian in the US can do, is trust in the Lord and not worry every minute about what is coming per these websites.
Yours in the Hearts of Jesus and Mary
