An illness that inflicts the person's mental state. Mental illnesses range widely from mild anxiety to severe schizophrenia. Depending on the severity of an illness, it can impact a person's life more than just mentally. For example, a person with borderline personality disorder might have a hard time holding down a job because of their mood instability. Other things that can be hard while mentally ill are keeping good hygiene, keeping healthy relationships, and keeping a good sleep schedule
John breaks up with Becky's best friend.
Becky: That was so sick of you! What, do you have a mental illness?

John: Mentally Ill is not an adjective. I have though, been struggling with depression. My mental ill ness doesn’t make me any less of a person.
