On pervasiveness, Sandberg said that it could happen to anyone - the belief that everything is awful but after she started to get back to work and had a meeting in Facebook office, she learned that everybody is loving. And for a few seconds, she forgot about the grief because she was busy. She realized that she should be grateful for the jobs, for her children and even for the time off she allowed to take. She gradually sees that her children can play more and cry less.

On permanence, she asked her rabbi for advice, and he told her to 'lean in to the suck' and accept the feeling. But one thing to remember is that it does not last forever.
