The Sandy Hook tragedy has got people talking worldwide. We may never know for certain if the suspect had a mental illness, but a lot of people are now wondering if mental illness could lead somebody to kill dozens of people. As a mental health advocate, I have an opinion.
While mental illness definitely can have physical symptoms, it's not visible like a broken bone or a deep cut, but I would argue the emotional pain is comparable. I live with anxiety and depression, two different mental illnesses, yet they both work hand in hand.
