We need to rejoice with others when they are joyful and weep with those who are sorrowful. When our brethren are afflicted we should be deeply concerned for them. We need to do whatever we can to be there for them in their times of trouble. We have to control our tongues so we don’t say anything we’ll regret.
Also sometimes bad situations linger and our mental anguish in those times may more difficult to deal with than the original problem.
And it’s possible to get low enough to wish we’d never been born but to keep on living in spite of our sorrow.
