How to comfort the sister-in-law who lost her father?

If people are sad because they have lost something, they can't get rid of it. There are two reasons. First of all, I feel guilty because I can't repay too much. Second, this lost thing supports your own needs too much. Losing it means that your own needs cannot be guaranteed.

If your sister-in-law is too sad because of the loss of her father, then look at that reason.

Is it because my father loved her too much in the past, and now he is sad because he lost the opportunity to repay her, or because he lost the support of his father's love?

These two situations, the way of comfort, are slightly different.

You talk to her like this: sister-in-law, we all know that you are sad because of your father's death. You have been sad for a long time. No matter whether you have been sad for too long, I want to ask you, is it because your father loved you too much in the past, and now you have lost the opportunity to repay, or because you have lost your father's dear support and are afraid that no one will love you so much in the future? If you want to repay your father's love, can you repay your father's love in a sad way now If you are worried that no one will love you anymore, can you get others' love in a sad way now?

Having said that, she will definitely jump out of the whirlpool of sadness, because people are rational, but sometimes they make small mistakes and return to rationality under the reminder of others.
