Jehanne,
You are a good man, so do not worry, but pray. I believe it is the Rosary that has saved these Popes from becoming formal heretics, St. Montfort says, "dear brothers of the Rosary Confraternity, if you genuinely wish to reach a high level of prayer in all honesty and without falling into the traps that the devil sets for those who pray, say your whole Rosary every day, or at least five decades of it ... For never will anyone who says his Rosary every day become a formal heretic or be led astray by the devil. This is a statement that I would gladly sign with my blood. "
Prophecy and private revelation, written for our time, confirms what we know from theology. St. John Bosco, exactly one hundred years before the Second Vatican Council told us this, "There will be an Ecuмenical Council in the next century, after which there will be chaos in the Church. Tranquility will not return until the Pope succeeds in anchoring the boat of Peter between the twin pillars of Eucharistic Devotion and Devotion to Our Lady."
which again shows us both that Marian devotion is the real solution to the crisis in the Church and that there really are perpetual successors to St. Peter during and after it. St. John Bosco also speaks of two Papal elections in this famous "Two Pillars Prophecy". Anne Catherine Emmerick also saw in our times (she said Lucifer would be freed and given great power around 50 years before 2000 A.D.) the satanic sect of Fɾҽҽmαsσɳɾყ given great power to attack and subvert the Church of St. Peter.
She saw there in Rome beside the Pope, many clergy and ecclesiastics, the vast majority of whom she said were lukewarm and indifferent. Her solution too was that we must pray night and day for the darkness to be lifted and for the good to prevail. So keep the Faith, continue fighting the good fight and do not be needlessly distressed. Turn to God and Our Lady in prayer and total consecration, for this is the time for Saints. The good God is with us always, even till the end of days, as He has promised. And as He said to His Apostles, He has told us all these things beforehand, so that when they come to pass, we may not away faint away with fear. The same is true for all striving to be good Catholics, even if they are more or less tempted by sedevacantism and despair.
Finally, Pope St. Pius X, whose first name was Giuseppe or Joseph, saw in a vision a Pope of the same name fleeing over dead bodies in Rome. Pope Benedict XVIs first name is also Giuseppe or Joseph, and personally I think there is a good chance, he is the Pope who is spoken of. That is only a guess, but if true, it means significant events are closer than we think, given that the former Holy Father is quite old and will probably not live much longer. Perhaps it will be the Russian invasion of Rome and of Europe, spoken of in many prophecies, that will finally bring the Roman authorities to their senses, prove to them incontrovertibly that Russia is in need of specifically being consecrated to the Immaculate Heart. In that case, it could well be Pope Francis and the bishops with him of whom Christ said at Fatima, that "they will repent of it, and they will do it, but it will be late." Let us pray every day with the holy children of Fatima, "Sweet Heart of Mary, be the salvation of Russia, Spain, Portugal, Europe and the whole world." and "By Thy Pure and Immaculate Conception, O Mary, obtain for me the conversion of Russia, Spain, Portugal, Europe and the whole world." God has promised us that after we have sufficiently prayed and worked for it, the Pope and the Bishops will consecrate Russia, Her Immaculate Heart will triumph and a period of peace will be given to the world.
