A 36-year-old woman attends a GP appointment. She has been struggling with her mood

A 36-year-old woman attends a GP appointment. She has been struggling with her mood and energy levels, saying that she feels exhausted and low all of the time. This has been an issue for her for several years, and she says that things generally get really bad around November time, and it isn’t until the springtime that she starts to feel better. She also complains of feeling cold “all of the time” and that this “drags her down”. The GP suspects she is suffering from seasonal affective disorder.
