It's such a shame. Ruby has everything going for her: attends a good uni, studys an interesting course, undivorsed parents, a sibling who although is a lot different than her personality wise cares for her (just read Martha's insta post for ruby's birthday), privilege, money, etc.
I understand that stuff could be going on behind closed doors and her life might not be as picture perfect as what I wrote above but from what we can see she has it pretty well and easy. Which is why I find it such a shame and feel sorry for her in a way. She wants to be the perfect student, daughter, sister, etc. But at the cost of her mental and physical health. I want to shake and yell at her about how lucky/privileged she is and to not take things for granted. But at the same time I just want to give her a hug because damn she needs a friend not just at the surface level. Someone who will call her out on her BS and be honest with her.
