"I'm So Tired..." (stylized in lowercase "i'm so tired...") is a song recorded by American singer Lauv and Australian singer-songwriter Troye Sivan. It was released on January 24, 2019, and was later featured as the lead single on Lauv's debut album, How I'm Feeling. The song reached number eight on the UK Singles Chart, becoming both artists' first top 10 there. It also reached the top 5 in Ireland, top 10 in New Zealand, and the top 15 in Australia.
Sivan remembers "Fully flipping out" upon being shown the track by Lauv during a writing session. The track went through several variations. At one point, the chorus featured four on the floor drum beats, although this version "felt really good". According to Sivan, it felt like a remix and that element was eventually dropped]. Lauv would go on to call the single an "accidental duet" explaining " he [Sivan] just sounded too good singing it, so I think it was just natural to do the record together.
