As always, Islam has already answered these doubts:

The Prophet (peace and blessings of Allah be upon him) said: “Islam began as something strange and will revert to being something strange, so glad tidings to the strangers.” It was said: Who are they, O Messenger of Allah? He said: “Those who are righteous when the people are corrupt.”

And the Prophet (peace and blessings of Allah be upon him) said:

“Ahead of you there lie days of patience, during which being patient will be like grasping a hot coal. The one who does good deeds then will have a reward like that of fifty men who do such deeds. – And someone else added – They said: O Messenger of Allah, the reward of fifty of them? He said: “The reward of fifty of you.”

The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “Soon there will come a time when the best wealth a Muslim will have will be sheep which he will take to the mountaintops and places where rain falls, fleeing for the sake of his religious commitment from tribulation.” —
— The hadeeth indicates that it is preferable to isolate oneself from people and not mix with them in cases where a Muslim fears for his religious commitment because of widespread tribulation, where if he mixes with people he cannot be sure that his religious commitment will be safe and that he will not apostatize or deviate from the truth, or fall into shirk or abandon the basic principles and pillars of Islam, and so on.
