A 19-year-old who believed she had been labelled a "confused teenager" by mental health services, took her own life.

Chelsea Smith was found by her mother Claire Brennan at their property in Plains Avenue, Maidstone, on Monday, October 4 last year with the words “I’m sorry” written on her hand.

A referral letter from Kent and Medway NHS and Social Care Partnership Trust (KMPT) had been sent to the wrong address 10 months earlier.

The teenager had a history of mental health issues, including anxiety, and was last seen by her mum three days earlier.

Miss Brennan thought she had gone to stay at a friend’s house.

On the Monday the concerned mother reported Chelsea as missing to police, but hours later found her dead in the family’s summer house.

An inquest at Maidstone’s Archbishop’s Palace heard cause of death was suspension.

Coroner James Dillon read evidence which detailed Miss Smith’s struggles with mental health, including psychosis.

He explained how a report from Kent and Medway NHS and Social Care Partnership Trust (KMPT) heard she had told staff she would hear voices in her head, including a Pikachu voice from the video game Pokémon.

The court heard how Miss Smith would regularly lock herself in the room to play video games or watch films.

Further evidence from Det Sgt Buckland detailed how Miss Smith was found with an A5 notepad which included two suicide notes, including one dated September 29, which explained while she was locked away in her room she was having constant panic attacks which she didn’t want to burden her family with.

The 19-year-old repeatedly referred to herself as a burden, revealed she had previously attempted suicide from an overdose and apologised to her family and friends for what she was going to do.

One read: “I’ve given up. Life isn’t worth it. The voices in my head are getting louder. I want to be selfish one last time.”

In the note, which she described herself as a “rant”, Miss Smith called on mental health services to be improved for young people, claiming she was previously told by staff from the Children and Adolescent Mental Health Service she was a “confused teenager”.

She also revealed she was struggling with her gender identity and “didn’t know herself”.

Speaking during the hearing, Miss Brennan said she felt partly to blame for her daughter’s death and thought her efforts to get her a job had “tipped her over the edge”.

As the hearing closed it was revealed that a referral letter from KMPT which was meant to be sent to Miss Smith in December to help combat her mental health problems was sent to the wrong address.

Before ruling a conclusion of suicide, coroner James Dillon expressed concern that the KMPT’s correspondence had gone to the wrong address and called on the Trust to investigate.

said: “It is a little concerning that this significant correspondence was sent to the wrong address.”

He called on KMPT to find out what went wrong and make sure it is rectified.
