As parts of the city begin to reopen, some New Yorkers are excited to get back to the world they once knew. But for others, the idea of going back to normal is unexpectedly daunting.

Some psychologists are calling it re-entry fear.

NY1's Ruschell Boone spoke with Yuval Neria, Professor of Clinical Medical Psychology at Columbia University Medical Center to get some advice for people who are anxious about returning to a post-pandemic world.

Among his suggestions - ease into it. "Do it slowly, cautiously and with great understanding of the fears people are experiencing," Neria said.

Neria pointed to high rates of mental health problems and substance abuse linked to the pandemic. He urged people with serious symptoms of depression to reach out for professional help.
