"That's all in the past, don't be sad anymore."

Everyone has a different time to overcome grief, and some post-traumatic anxieties linger in their hearts for a long time. When we say that everything is over, we inadvertently deny their current feelings. We don't realize that past pain may still haunt and be recalled daily, causing them to lose their sense of security.
Accepting that their experiences have had a profound impact and listening more is better than a thousand words of comfort.
“There are many people out there who are suffering more than you.”/

Emotional pain cannot be judged as being more severe or less severe; all are experiences worthy of acceptance and sharing. This statement, while intended to encourage, makes the person involved feel small and weak.
"Don't overreact."

Everyone has their own limits of endurance. Some people easily lose their temper and have difficulty controlling their emotions in the face of mental pain. Be understanding and give them space to vent, time to stabilize their emotions.
When we say "don't overreact," we unintentionally make them feel like they have to suppress their pain, leading to more hurt because they feel unaccepted.
"Think about what you have."
By saying this, we emphasize that someone shouldn't grieve because they have other things in life. This can easily become toxic positivity, completely denying any emotional damage and downplaying the pain and hurt. Instead, we should help them come to terms with their losses and gradually recover.
