This Signs of Mental Illness Infographic depicts various symptoms of mental illness. It is too easy to go about daily without noticing physical or psychological illness signs. Our bodies have built-in warning systems that alert us when we need to pay attention. Most people experience mental health issues from time to time. However, a mental health concern becomes a mental illness when ongoing signs and symptoms cause frequent stress and impair your ability to function. Symptoms can generally be managed with a combination of medications and talk therapy (psychotherapy), as illustrated in this Signs of Mental Illness Infographic.
