Grief Psychology - Is It?

Grief is a painful response to a sudden loss or change that you didn't ask for. It's basically, it's when your brain tries to protect you from a truth by distorting your perception of what that truth is. Denial is a defence mechanism. Defense mechanisms can be negative. They can steerism in ways of living that causes pain or interfere with our relationships with other people. But they also exist for a reason, and aren't necessarily always like that.
