I looked at your profile and your primary concern is schizophrenia and I'm assuming your DX. With schizophrenia, there is something known as the "flat effect" or "blunted affect" which a person shows little to no emotional expression and their reactivity to emotions isn't as intense compared to your normal folk.. I'm not saying all people with schizophrenia have that but that is something that is symptomatic of schizophrenia.
