Sad headcanons for AoT characters

What if Erwin writes little notes of appreciation to the Scouts before they leave the walls for an expedition...?

What if Levi has panic attacks every time it rains because it reminds him of when he lost Isabel and Farlan...?

What if Hanji cries herself to sleep after an expedition because she feels overwhelmed by the deaths of her comrades...?

What if Eren stays up all night, several days a week, because he can't get the screams and cries of his friends out of his mind...? He may also bite his thumb out of anger/ frustration.

{This is another Levi one (And Ereri)}

I have a headcanon that whenever Levi has a panic attack, Erwin/Hanji searches for Eren so he can go lay with Levi and calm him down. I have a feeling that Levi does the same for Eren when he's upset.
