Am I the only one?

Am I the only one that isn't super excited and so in love with my sonograms? It's the oddest feeling to know I'm pregnant and not be overly excited, happy or on cloud nine about it. I'm terrified. This wasn't supposed to happen. When my immediate family talks about it, I don't even crack a smile. More like my eyeballs are bulging out of head trying to grasp what's really happening still and I'm 11 wks. By now this should have sunken in. I haven't told anyone else or announced on Facebook and keep pushing it back. I partially feel like this is some cruel joke and I'm waiting for the bottom to fall out. Am I on this boat alone? I feel like a horrible person for not being over elated yet about having a baby.
