Lack of appetite/nausea/disgust at food - anorexia or depression?

Context: have had a restrictive ED for 5+ years, have CPTSD and OCD, and have had depression and anxiety since I was young (those two sort of take a backseat though,as the other three are trying to drive the car off the fuckin cliff 😅)

ANYWAY I've been experiencing loss of appetite/nausea/disgust at food this most recent relapse, and I was hoping it would get better with refeeding (I'm about a month into inpatient treatment) but so much food still just gives me the ick ☹️ I also have no/very occasional hunger queues, even if I restrict, just... nothing.

Food used to be something I was passionate about - even when ill ED-wise I loved flavour, and cooking, and consuming content about food (as to be expected if your in a state of starvation and also I genuinely am quite passionate about cooking/baking). But recently it all just seems... gross.

I know that lack of appetite and interest in food can be a symptom of depression, so I was wondering, could I be more depressed than I thought? I don't know if I am because I'm SO anxious/agitated all the time while I'm here. I'm on a pretty hefty dose of antidepressants, and have been for some years (although this was reduced slightly before my relapse). The psychiatrist is going to put my dose back up and see of that helps but yeah.

It just feels like my body and brain are responding to food differently than in previous recovery attempts? Has my anorexia really got so strong it's made food seem gross? Just an excuse to avoid it? Or maybe depression at play? I feel so confused 😕 Anyone related?
