I've noticed this in myself for a while now. My emotions seem to be pretty 'flatlined' on a daily basis. There aren't many things that make me happy, sad or otherwise. People tell me I'm too serious. I think I've always been that way though. When I was a kid and I'd hang out with people my age, I would get told a lot that I looked and acted older than the other kids I was hanging around with. I think part of that was me just being 'serious', whatever that means. Well, I'm far from being a kid now, but I still get told that I'm too serious and I never smile. Anyone else ever feel like this?
