1. insidiously

   Healing Is Difficult is the second studio album by Australian singer and songwriter Sia. It was released in the United Kingdom on 9 July 2001 and in the United States on 28 May 2002. In the UK the album's first single "Taken for Granted" was released in early 2000 and peaked at number 10 on the UK Singles Chart. A low-budget music video was made for around $50. The follow-up "Little Man" peaked at number 85, and the song received a two-step garage remix which was popular at the time. A third single, "Drink to Get Drunk", was planned. However, only the "Different Gear" Remix received a limited release across Europe, promoted as "Different Gear vs. Sia". Its peak position was number 91 in the UK, 85 in the Netherlands, 55 in Belgium and number 1 on that country's dance chart. The fourth and final single planned was "Blow It All Away", which was re-recorded as "Throw It All Away" due to the September 11 attacks. However, the single failed to surface. The album had no chart success in the United Kingdom due to lack of promotion. The track "Sober and Unkissed" was originally featured on Sia's first solo album OnlySee under the title "Soon", and "I'm Not Important to You" was originally performed by Sia with her band Crisp for their album The Word and the Deal in 1996 as the track "Sia's Song".
