"When you share a bad feeling with someone who cares about you, this person will remove some of it from you, making you less sad about it and the other person a little more sad, but it doesn't matter, because they care about you and helping you to suffer less nullifies the sadness caused by it.
When you share a good feeling with someone who cares about you, this person will be as happy as you are, therefore duplicating the happiness."
This is why it is important to share your feelings with people who care about you
What about it though?
