My mom didn't tell my I was emotional until college and trust me I knew by then. She more just said that I've always been like that. So i wouldn't say that's why it's happened. I do believe that some people are just born super emotional or sensitive. Serious emotions I think make people uncomfortable. I think atleast half of the world doesn't know how to deal with the other half. My sister does not understand my emotions. She just hoped she didn't grow up to be like me. I tease her about not being able to be truly happy.
I have to admit my husband is like this emotional dead spot. He's so peaceful. that seems to be his only emotion. It has it's down sides, but mostly they are worth it...
