I'm so emotional!

Andrea
Omg I hate all the emotions. For the most part I'm very happy. But I seem to just get my feelings hurt so easily. If me and my fiancee fight or disagree.. Or if someone gets to hold my baby but I really wanted to and I don't wana be rude. I cry. And once I start crying it takes forever to stop. My fiancee just doesn't understand .. I feel he gets mad at me. What do I do
