Nauseous, not eating but hungry at 10 weeks

So I’m 10 weeks and I’m constantly feeling sick so I cannot eat but I’m soooo hungry 😩 this has been going on for 4/5 weeks and honestly it’s making me so angry/upset. This is my second baby but I never felt like this with my first 🤷🏻‍♀️ anyone else feeling like this? Or am I just being daft? I’m sick of people telling me to ‘just eat’ because I would if I could!
