The trial of a GP for the manslaughter of her disabled daughter has heard details of a note found in her handbag the day after her daughter's death.
The note described how she could not watch her daughter suffer any longer.
The evidence was heard on the third day of the trial of Bernadette Scully of Emvale, Bachelor's Walk in Tullamore, Co Offaly.
She has denied the manslaughter of Emily Barut by an act of gross negligence.
The prosecution alleges she gave toxic amounts of the sedative chloral hydrate to her daughter on 15 September 2012, before taking an overdose herself.
Yesterday Ms Scully’s partner told the court that on the day Emily died he saw an envelope with some writing in Ms Scully's car but she took it from him before he could read it.
The day after her daughter's death gardaí found the note in her handbag.
On the outside of the envelope her partner Andrius' name was written.
It said: "If anyone thinks I am awful for doing this you should have listened to poor little emily crying the last eight days. I love her dearly. Bernie.
Detective Garda Colin Lawlor said the envelope was sealed and he opened it to find a hand written note on both sides of a page which said:
"I'm sorry love 15.9.12. Andrius my love I love you more than you will ever know, you are what has kept me and Em alive over the last five to six years.
"I do not want to die, I can't let Emily's suffering continue. I can't watch it any longer. The pain is too big. The struggle is too hard the loneliness and isolation too much.
"I'm of sound mind and I leave everything belonging to me to Andrius, he needs a home."
She also included messages to members of her family. The note ends: "Good bye my love, thank you for all yo did for me for Em. my love Bernie x and Emily x."
Garda Lawlor said he also removed a number of different medications found at the house.
The trial also heard from Elaine Donohoe from the National Poisons Information Centre at Beaumont Hospital.
She said on 15 September 2012 she received a call from someone identifying herself as a GP in Tullamore, Dr Scully. She enquired about a patient who had taken tablets and asked for information about the lethal dose.
Ms Donohoe told her it was not the centre's practice to disclose a lethal dose but she could say what the toxic dose would be.
She said the caller said the patient was an adult female 60kg who had taken a certain amount and was asymptomatic having taken it four hours previously.
She informed her that this would be the toxic dose and recommended further assessment in hospital. Ms Donohoe said the centre received a lot of calls from the public and from medical professionals.
She had to ask the caller a number of questions rather than having the information volunteered but she said the questions were answered without hesitation.
Dr John Michael Morris, a pharmacist and retired director of Irish Medicines Board, said chloral hydrate was a sedative which causes sleep and sedation.
He agreed in cross-examination that the sedative would remain in the system for longer or be slower to be metabolised in a smaller, inactive person than in that of a larger, healthy and active person.
Defence Counsel Ken Fogarty said Emily weighed just 32kg, had scoliosis and was unable to sit up unaided and was not mobile.
Dr Scully has denied the charge of manslaughter. The trial continues this afternoon.
