yep i'm pretty sure this kind of crash course diet might lead to an actual crash in the future if you're not careful. it might be best if you are having trouble with an eating disorder to talk to a doctor before self-medicating. barring that, if it actually does help then i'm happy for you. but you have to eat or you will start to become weak and eventually you won't be able to remain conscious for more than a couple of hours at a time.

i know i'm just some guy on the internet who doesn't know anything about you but i'm sure there are other ways to get you on the right path
