That happens to very many converts to Catholicism. I experienced actual rejection from my Protestant friends. And it took some time for my father and mother to accept my conversion. However, in the end, both of my parents were ministered to by a priest in the last hours of their life. Deo gratias.
My parents are still Protestants, but they basically shrugged at our conversion. The only family member who was deeply hostile was my husband’s brother, but they’d never gotten along anyway, and it’s blown over.
