Taking Sinemt 25-100 Tid. Several Months Ago Started To Obesess

taking sinemt 25-100 tid. Several months ago started to obesess on life event from 50-yrs ago. Can't get this out of my mind. Have been seeing therapist and this has led to more unanswered questions about past event. Tracked down one of the parties but each question I asked was responded to by conflicting answers. Other party deceased 40 years ago.
