I think it's also all the different issues in her life, no proper support from her boyfriend who she hasn't seen in like 3 years, no support system from friendships as she has none, having to move back home with her parents etc.. I remember at the start of the year when she started doing those clothing hauls with kids clothes and tiny tiny clothes, we all knew then it was getting toxic, I just have a feeling it's only going to get worse before it gets better. I really dislike Emily but feel for her having no proper support (of what we can see)
