Have you tried sitting down and playing with her toys with her..singing playing outside playing games...maybe she is bored. My 17day month old seems to go days without eating anything then she will stuff her face lol..hang in there!!
If it gets to the point of you raising your voice again maybe try stepping away into another room for a minute to cool off, try counting to 10 taking a deep breath then come back to your LO and try sitting eye level with her and telling her how you're feeling in a calm friendly way. and try to play with her like Abbichrysler3312 suggested
