Some people, after extreme collapse, regardless of the consequences, regardless of the occasion, or cry or make trouble, hang themselves, or remain silent, do not eat or drink. There are two possibilities:

Or because of excessive sadness and anger, I lost my mind and my emotions were no longer controlled by nerves. Or deliberately show it to others. Rolling, crying, wailing, trying to die. The former is a complete collapse, and the latter is an opportunity to make trouble. The former is reckless, while the latter strives for the consequences. There are also some people who will consider the consequences even after the collapse.

They don't make trouble by crying in public. But adopt a silent attitude. Even if you want to die, you should find a place that won't affect others.

This kind of person is what we call a "dead end". He just contradicts himself at one point. Of course, the external cause may be yourself or others.

In view of the above, this kind of person still has some self-control, which is not a complete collapse. Therefore, we cannot generalize. Can't say reasonable, also can't say useless. We should distinguish between people and situations. As the saying goes, words are the key to happiness. For such people, we should be patient and reasonable, and let them get out of the brink of collapse and get a new life.
