Neurosis

A mild form of mental illness, in which subjective experiences of emotional distress are common but contact with reality has not been lost. Examples include anxiety disorders, depression and eating disorders. It is also called psychoneurosis.

Neurosis can in many ways be distinguished from the more severe psychotic mental disorders, such as schizophrenia and manic depression (bipolar).

Bipolar disorder

Also known as manic depression (dated), bipolar affective disorder is a severe, debilitating psychiatric illness characterised by alternating periods of elevated mood and energy levels (mania or, if milder, hypomania) and lowered mood and energy levels (depression). It runs on a continuum from subsyndrominal to extremely severe but is generally regarded as one of the more serious mental illnesses, esp. in its classic form (type I). During severe manic or depressive episodes (particularly the former), psychosis may emerge, often making it indistinguishable to schizophrenia. Often trivialised in popular culture and trivialised as "just mood swings", it is, in actual fact, one of the most severe psychological conditions and hell on Earth for those who genuinely suffer from this devastating disease, as well as for those around them.

Bipolar disorder is a cruel affliction.
