This may include symptoms such as anxiety, depression, stress, mood swings, substance abuse, eating disorders, phobias, obsessive-compulsive behaviors or thoughts of self-harm. Poor mental health can be caused by a variety of factors including genetic predisposition, environmental influences, trauma, and life stressors. It is important to address poor mental health through professional help, support from friends and family, and self-care practices such as exercise, meditation or therapy.
