Yes, that does sounds like anxiety...I've experience that when I was diagnosed with anxiety, no appetite, not hungry, I would only eat when I feel faint, dizzy or shaky...have you checked with your dr to talk about your symptoms? Do u feel any different (weird feeling/thoughts)? Maybe you need to see your dr if you still don't have the appetite to eat.
Good luck and keep us posted...take care!!
sounds like no apetite and your body telling you it needs nutrients to me.
