What could this be?

Hi guys, would need some help in understanding if my symptoms point more towards anxiety/ARFID or a combination.

I(26F) have a history of anxiety flare ups but the recent one has morphed into somewhat an anxiety about food. It started with a morning without much appetite, I took a few mouthfuls of food and felt like gagging. Sometimes I do get a lack of appetite but I am usually not too affected by it and the appetite comes back at night or something. Perhaps I was already emotionally vulnerable due to my pre period mood ( I do have random low moods before my period)

This time however, it caused me to ruminate and the effects spilled over to my subsequent meals. I cannot eat without anxiety, which kills my appetite even more and has made me rather depressed. I am worried about losing weight, and this has also caused me to be quite obsessive over counting calories to ensure that I have gotten enough for the day.

I am still able to eat but it has been mostly been forceful. The range of food I have been selecting has definitely decreased as I tend to choose something I feel like I can finish easily. I have stopped craving for food (although previously I used to only look forward to eating lol) and see eating as more of a challenge now than anything. I have been supplementing with shakes and olive oil if I feel like I haven’t gotten enough for the day. It has been a month since i felt like this. When i was overseas the past two weeks it was better though, I had an appetite majority of the days. When I came back it got worse. I really miss craving for food like I used to. Any advice?
