Toddler help

I need help with feeling helpless with my toddler. He screams, which feels like all the time and I can’t figure out what he wants. He is almost 2 and only starting to talk so obviously communication is an issue. He will scream for food. I end up putting everything in front of him he would eat and he just keeps screaming. I try to be compassionate but I can only handle the screaming for so long. The helpless feeling is starting to make me buffer with food. I have not eaten like this in over a decade. i try to sit with this feeling but can only handle it for so long when it is accompanied with getting screamed at. please help with how to work thru this.
