About Mental Illness

Millions of people live with various types of mental illness and health problems.

Mental illnesses such as bipolar disorder or schizophrenia just don't happen overnight. Children, adolescents, and adults will notice different changes in terms of the way they think, feel, or behave over time. People will usually feel like something is just not right.

Though medical professionals suggest that once someone feels multiple symptoms, that's when they should seek help, according to
