Feeling hopeless after reading St. Leonard of Port Maurice’s Sermo - Is salvation even possible?

I just read this sermon by St. Leonard of Port Maurice, and I’m honestly feeling completely shocked, scared, and hopeless. The story about the woman who died, saw the judgment of God, and learned that out of 60,000 people, only three were straight up saved and two went to Purgatory, has shaken me to my core. It’s honestly terrifying. How can catholics feel secure knowing that so many people are lost?

What really struck me was the idea that salvation seems so rare, and it feels almost impossible for someone like me to be saved. It’s as though the only way to have a chance at Heaven is to give up everything, maybe become a monk, live in complete seclusion from the world, lock myself in my bedroom and pray the rosary nonstop. Also, my family and I are protestant, and with this information, it seems impossible for protestants to be saved, thus, confirming no protestants can be saved, because the conditions for someone to be saved are extremely restricted, and according to St.Leonard of Port Maurice thought, if it's so difficult for catholics to be saved, then it is impossible for protestants to be saved.

Honestly, I don’t see how anyone can live like that, with this constant fear and doubt. It feels like the only option for anyone is to cut off everything I know such as my family, my friends, the life I’ve built and completely dedicate myself to a life of severe sacrifice and seclusion, out of fear of Hell, but even then, I’m not sure that’s enough. The children who saw Our Lady of Fatima did such things, I've read Jacinta and Francisco were capable of going entire days without eating, or drinking a drop of water even in the middle of August, walking around all day and in their sleep at night. I also read Francisco even stopped going to school, and instead, he preferred to hide in the church, praying for sinners and never again ate properly.

I’ve already tried to be better, but this sermon makes me feel like no matter how hard I try, it will never be enough. I’m honestly scared and confused about where I stand with God.

Does anyone else feel this way? Like, how can anyone live up to such a high standard? Is there even hope for someone like me who is struggling to balance faith with the realities of life? How do you keep from feeling crushed by the weight of this kind of message?
