Alogia - poverty of speech

Does anyone else experience Alogia, poverty of speech? It’s one of my major symptoms, even with medication. It’s a very frustrating symptom because I seem like a jerk when I’m socializing with other because I seem uninterested. It also makes therapy very difficult because I spend most of the session in silence. I do write to my therapist and that helps but not during the session. It has ruined relationships with friends and some family members because people don’t understand why I can’t just speak.
