One guy once went through a very bad period. Work malfunctioned, feelings also fell to the midpoint. He started telling his best friend, then telling colleagues, posting vague statuses online. Initially, everyone asked and encouraged. But then, words of comfort gradually faded away. Some people started to be silent. Some people changed the subject. And some people "gossip" about it with hidden glee at a drinking party.
Everyday life is like that. People may love you, but may also just be curious about you. Some people really want you to be better, but some people just want to know how bad you are. These two emotions are sometimes very difficult to distinguish, because they all start with the same question: "How are you?". Not everyone is bad. It's just that each person carries their own world, with their own priorities. Your sadness, for you, is the center, but for others, it may just be a small piece in many things they are thinking about. And in some cases, it even becomes a way for them to feel better, a very instinctive comparison that few people admit. One of his colleagues, after a breakup, chose to remain silent. She still works, still smiles, but talks less. Some people say she is "strong", some people say she is "cold". She just smiles: "There are things that I keep for myself, they are still intact. Telling too much, they are distorted without anyone knowing".
That does not mean living alone with everyone. People still need to be shared. But perhaps, the more important thing is to choose the right person to tell, at the right time to speak. Otherwise, sometimes, silence is a form of protection. Not to hide sadness, but to keep it from being consumed by unnecessary looks. There are emotions that, when kept, will subside, will find their own form. But when told repeatedly, it is easily prolonged, exaggerated, even misunderstood. Living long enough, people will realize that not all sharing brings relief. There are times after telling, we feel emptyer, as if we have just lost a part of privacy without receiving anything commensurate.
So, learn to keep it and that silence makes the sound more meaningful.
