I never eat ):

hey guys! I need some help. So recently I've moved out and I'm living on my own. I started eating less cause I didn't have much food, but now my appetite is completely obliterated. I have food to eat, I just cannot make myself eat it. The thought of eating makes me feel nauseous and when I try to eat, I get full like 4 bites in. My boyfriend brought me zaxbys today and I only ate like 6 fries and half of a nibbler 😭 idk what's going on, I want to eat but my appetite is just gone. And I just recently got sick too so its gotten worse cause my appetite sucks when I'm sick. Any tips, ideas, or foods you would suggest that would help me get back on track? Keep in mind I'm on a budget!!
