Bonjour Sophia !
When using the negation ne ... pas, you need to remember the two words are going on each side of the conjugated verb, as such:
J'ai faim, je ne mange pas.
Have a look at the related lesson: https://kwiziq.learnfrenchwithalexa.com/my-languages/french/view/601
I hope that's helpful!
À bientôt !
