Is an abrupt calmness in a person known to have serious depression a potential warning sign of suicide contemplation?

An abrupt calmness in a person who has previously exhibited signs of serious depression can indeed be a warning sign of potential suicidal contemplation. This change in demeanor can be particularly concerning because it may indicate that the individual has made a decision to act on their suicidal thoughts. In some cases, this calmness can arise when a person feels a sense of relief from having resolved their internal struggle and may perceive that death is the only escape from their pain.

It's important to recognize that individuals battling depression often experience periods of intense emotion, and a sudden shift to calmness can mean that they have reached a critical point in their mental state. This calmness does not necessarily mean that they are feeling better; rather, it could be a sign that they are contemplating actions that may lead to self-harm. Monitoring such behavior and providing support or intervention can be crucial in ensuring their safety.
