Obviously, I can't speak for you. I have something called alexithymia. In essence, it means I don't know what my emotions are telling me. I also have an inability to connect with, bond with, or have feelings toward another person (except transiently under certain circumstances). Add to that socially non functional, because I cannot recognize body language, facial expression, innuendo or implied comments, or even intonation. Plus words seem to change meaning frequently, depending on context. All of this seems to be related to my autism. It is possible that you may have some of these problems as well, they are not unique, but apparently rare all at once in the same person. Take a good deep look at yourself. One thing I have learned is that smiling at the wrong time or situation is worse than not smiling at all. Likewise, the wrong facial expression can be worse than none at all. It took me a long time to really learn this.
