Why do some people expect you to be right mentally after being abused or having some type of traumatic experience?

They've probably never had to deal with it themselves. Or if they have, they hide their trauma and expect you to do the same.

Because they have a limited brain.
I understand.

It is that way with all cognitive and emotional challenges. The injuries are not visible except through expressed dysfunctional behavior.
If you are able to get therapy you are fortunate but you won’t get sympathy.

I don't mind so long as the traumatized person doesn't use their past to excuse abusive behavior. But other than that, I agree that it's unfair to expect victims to magically feel better and live a normal life.

Shoving you into the light is easier then sitting with you in the darkness. People are selfish.

Some people don’t have the mental capacity or either the emotional depth to understand.

Everyone carries their own burden

You’re right
