Mental ill-health refers to a range of conditions that affect a person's mood, thinking, behavior, and emotional well-being. It can include things like depression, anxiety, bipolar disorder, schizophrenia, and PTSD. Mental ill-health can have a significant impact on a person's ability to function in their daily life, and it can also impact physical health. It's important to note that mental ill-health is not a personal weakness or a character flaw, and it can be treated with therapies like talk therapy and medication.
