I agree with @Mahamid Frauded Me (by the way, I love your username lol) this whole family does need to go to therapy. They all use Anna as a scapegoat to blame all of their problems on. I have a soft spot for Anna because she just looks so sad all the time. She always sounds very nervous when she speaks, like she is hoping she doesn't say the wrong thing. Amber and Trent basically turned the whole family against her, so any mistake she does, they never let her forget it.
Jonah is just so immature. I can't believe he actually blamed Anna as his reason for failing math 🙄 he was really grasping at straws. He seems very spoiled; his mother still makes his bed, cleans his room and probably does his laundry for him!
Elizabeth is just like Amber, always having to prove someone wrong. Her personality is really grating. The way she was speaking down to Anna was really disgusting. Anna is nervous to leave home, that's understandable. But, Elizabeth was making it seem like the way Anna was feeling was wrong. It's easy to tell that Elizabeth doesn't really like Anna.
Alex is a spoiled brat and the way everyone treats him like he is a toddler is really disturbing. He throws temper tantrums and cries when he doesn't get his way, yet they all act like it's normal. But for some reason, they all dislike Anna.
