grief

Grief is a strong feeling of sadness and loss when something or someone important goes away.

You might feel grief when a loved one dies, but it's not just about death. You can also experience grief after the end of a relationship, like a breakup or divorce, or even when you move to a new place and leave behind friends and memories. Sometimes people talk about feeling grief during big changes in life, like losing a job or going through a serious illness. The word "grief" describes that deep emotional pain that comes with saying goodbye to something familiar.
