You probably know what lactose intolerance is, right? Well, the same happens to me regarding emotions: I can't process them well. Probably because they are intended to be something somewhat irrational, and whenever I feel something that is not numbness, I feel nervous because I don't know what to do with the data I'm receiving. In fact, it's like my mind is blurry and I can't articulate ideas, thoughts, words.
Whenever I feel something, I try to quantify the amount of "feeling" I'm experiencing and compare it to previous experiences feeling that feeling. Then I try to analize why I'm feeling that way at that precise moment (i.e. trying to identify the source that triggered chaos inside me) and why the source triggered that specific emotion. Then I analize why I have the predisposition to feel that emotion given that specific trigger and if has always been the same or if it's been different before. And theeeen, I analize what the emotion is, if it's raw, pure X emotion or a combination of other emotions (and probably assign percentages to each component), and then I do all of the above with the feeling I have about feeling that way (how I feel about feeling that way).
Having emotions makes me isolate for a while so I can reflect, but most of the times I'm either a psycho that doesn't feel anything when crazy things happen or I freak out because I have to react quickly and I can't because I don't have enough time to organize my defragmented emotion bits in a way I can feel comfortable about it.
About other people's feelings, I'm very good at determining what they are, I'm like a Sherlock Holmes of hidden features, I read people very well just by analyzing the way they talk, move, their gestures, etc... unless those feelings are towards me. Then I'm basically blind. For me to do a good read, I need people to interact with other person that is not me. When I try to see what others' emotions are when they're talking to me, everyone is either too good or being sarcastic. I do not understand the "worried", "sad", "kindly trying to help", "just helping so you stop bothering", etc
