Nonstop crying

My baby will constantly breastfeed throughout the day sometimes...today was one of those days where she's constantly eating and crying... I researched the symptoms and came across GERD especially silent reflux. I'm ready to change my diet and have been positioning her differently and breastfeeding to empty out one breast before offering the other. It was frustrating for me seeing her cry, made me feel very emotional and sad... She's been wetting and pooping her diapers just fine and is eating enough... I'm feeling that maybe the extra chocolates, eggs and mayo in my diet may be contributing to her tummy upset....anyone else experience this?
