Mental illnesses are psychological and emotional disorders that affect the way people feel and behave.
Some people experience mental illness for only a short time. For example, some parents experience postnatal depression in the weeks or months after having a baby. Likewise, anxiety or depression can sometimes happen in response to stressful life events.
But for people who have conditions like bipolar disorder, schizophrenia, and chronic anxiety or depression, mental illness can be a long-term experience. These people might need lifelong treatment to manage their illness.
For many people, mental illness isn’t a life sentence. With the right treatment and support, it’s possible to recover from mental illness and live a happy, healthy life."(https://raisingchildren.net.au/grown-ups/family-diversity/parents-like-me/parenting-with-mental-illness)
