I was thinking, NM. DON'T listen to The Beach Boys or any other music that makes you happy as you might always associate it with this grimbly period. In the fab autobiography, Lost In Music by musician/writer, Giles Smith (ex-Cleaners From Venus, check them out when you recover and Martin Newell), the author is gravely ill for several months. He eschews his favourite music to only listen to the glum The Blue Nile and subsequently didn't spoil Motown, Trojan and old power pop records for himself. He never listened to The Blue Nile again.
