Is there such thing as mental Anorexia?

ive been reading about anorexia alot and all it says it that the usual symptoms are loss of weight, thinning bones, brittle hair ect. but i was wondering if there are some mental signs that i could look out for for my own sake? i know one is hoarding recipes ( i do that quite a lot, i have nearly 50), are there anymore a bit more obvious ones?
