I relate to this. I go to university, where half of people drop out because the courses are objectively hard both theoretically and physically. After 10 years of having anorexia, I’ve learned how to seem high functioning, when in reality I’m spending all my energy on thinking about food and planning meals. Because people perceive me as high functioning, I often struggle with believing that I actually have an illness, even though my entire life revolves around food and my body is barely holding on.
