I was just wondering how can i overcome a lack of emotions?

Evaluation 1st: A thorough psychiatric evaluation is the first step in determining the cause of "lack of emotions." some possible issues are depression, the numbing phase of ptsd, dissociative disorders, certain psychoses, etc. Some drugs can result in this as well. Please consider consulting a psychiatrist, psychologist, or other mental health professional for help -- don't try to manage all on your own.
