Dear Amelia is a pop rock and alt-pop album that explores themes of unhealthy relationships, mental illness, and suicide.

The album was promoted with five singles, a tour across North America, Europe, and Australia, and the "Letters to Amelia" initiative.

[7] She has also worked with Mike Shinoda, Travis Barker,[1] and Machine Gun Kelly,[8] went on tour with Yungblud, and contributed to the soundtrack of the 2020 Disney+ film Clouds.

She is also based on people in her life that have committed suicide,[2] and the inspiration behind the character was the feeling of "wanting to open up but not knowing how".

[8] The album was also written about challenges faced by young women, such as mental health, unhealthy relationships, and problems with identity.

[1] Oshen Douglas-McCormick from Clash believed the album "takes a dive into [Renforshort's] brain" and reads like a "lovesick diary in a tearjerker romance movie".

They further wrote the album tells a story about the ups and downs of love and "self image in a time when youth has become a painfully self-aware experience".

[12] Neive McCarthy of Dork called the album a love letter to the complexity of feelings and said that Renforshort "navigates growing up in all its different hues".

[16] For The Line of Best Fit, Ims Taylor said Renforshort "takes us on a winding journey through her coming-of-age psyche, mixing genres and pulling from unexpected places to put the narrative of Dear Amelia together".

Renforshort described the songs' subject matter changing from "surface-level relationship troubles" to "I just want somebody to tell me that I'm OK because I don't know if I am.

[8] The opening track of Dear Amelia is "I Miss Myself", which contains simple guitar strumming, a soft piano, and emotional vocals.

[17] Greta Brereton of NME wrote that while it is "filled with bright melodies and sweet vocals" and a "bubbly track" on the surface, "the lyrics convey a darker story".

[8] The indie pop[1] "We'll Make This OK" is a collaboration with Barker and blends guitar riffs with "video game synths" according to Taylor.

[12] "Don't Come Back" is an emo pop song that has a "sprawling backdrop and gorgeous, ethereal melodies" and was compared to the 1975 and Muna by Taylor.

[15] The sad and slow ballad "Let You Down" features Bugg[8] and has lyrics that were compared to Olivia Rodrigo by Taylor.

[21] The North American leg took place throughout September and October 2022, with Joey Valence & Brae as a supporting act.

[23] Dear Amelia was released by Interscope Records on July 8, 2022, through digital download, streaming, LP, and CD formats.

[12] McCarthy wrote: "From nursing a friend through hard times to dealing with toxic relationships, each topic is handled with sage wisdom".

[16] Taylor thought that Renforshort's "lyricism shines the brightest through the dreamy emo-pop haze she's built in her music".
