Sudden Loss of Appetite

Patient: I abruptly lost my appetite a few days ago, and since it happened I’ve been eating probably no more than 1000 calories a day. I ate almost nothing yesterday, and this morning I just woke up feeling awful. I’m starting to think there’s something seriously wrong with me.At first, I thought that maybe I lost my appetite because this boy was giving me butterflies (ew, corny). Which has happened before, but it never lasted this long.I’m a 19 year old female by the way.
