Why do people attempt suicide when they appear to feel better?
Sometimes a severely depressed person contemplating suicide doesn’t have enough energy to attempt it. As the disease lifts they may regain some energy but feelings of hopelessness remain, and the increased energy levels contribute to acting on suicidal feelings. Another theory proposes that a person may “give in” to the disease because they can’t fight it anymore. This relieves some anxiety, which makes them appear calmer in the period preceding a suicide attempt.
