I get this as well. It is a defense mechanism called intellectualization. For me, it typically kicks in when I get stressed out, overstimulated, or if I am thinking about traumatic events. It can be very difficult to recognize emotions in this state. However, I have found that talking about my experiences, and how they have made me feel, forces me to feel those emotions and helps me move on from them. Specifically, the act of vocalizing it to another person, helped me feel what intellectualization had muted. It will be emotionally exhausting if you decide to do it though.
