This is why comparing yourself to them in terms of the healing process isn't going to help you in any way, shape or form.

This is why you can't expect them to feel anything close to what you're feeling right now, because you and them are on a completely different stage in the healing process.

Instead, focus on taking care of, solving and healing what you are experiencing right now.

This happened long or shortly before they physically left.

Simply put, because they have been prepared and you weren't.
