Confused about digestive symptoms TW: talk of behaviors

I’m in a semi relapse and having a ton of nausea and vomiting. Every time I eat now I get nauseous unless it’s something like broth or crackers. I now have to go off my Latuda because it makes me so sick when I try to drink an Ensure then take it I end up vomiting repeatedly. I can’t tell if I’m subconsciously “making” myself vomit or if I really have to. I have atypical AN not bulimia but in the past I’ve had bulimia. I can’t tell if it’s coming back now. It’s like I don’t eat much at all but if I do eat I want to throw up or I do throw up. I’m eating less now than before I went into residential in January. And the weird part is I don’t even feel that bad physically. But I know that won’t last forever.
