Again with this thing?! this bitch makes no sense! I hate this type of people/characters that think others can understand them without them saying anything about themselves, like they expect people to be able to read their fucking minds, so stupid!
as someone who were like this before, i don't think she wants to be understood because maybe of the belief that "no one will understand me anyway, so I'll just push them away when they did something that triggers me instead of telling them what's up". Not saying that it's justified, because it's still unwise, but it could explain her actions. But this is just me putting my own self in Liz's POV.
