Mental Illness or Personality Traits?: The Roots of “Bad” Behavior in Your Partner

When you look at the list of symptoms for various mental illnesses, they can sometimes parallel the traits we generally do not desire in a partner, such as:

  • mood shifts (often unexpected)
  • elevated self-esteem
  • impairment in completing activities
  • irritability
