what's wrong with me?

I've been feeling super tired, little dizzy and always wanted to throw up for 2 days now. Whenever I have some food, i feel like throwing up after that so I don't want to eat anything at all, even fruits or chocolate 😩. My head and my body hurt too. I know I don't have food poisoning. Have you guys experienced something like this before? Any advice for me? Thank you so much and have a good Friday ❤
