A man who stabbed his mother to death at her home in East Sussex has been given a life term and told by a judge he needs psychiatric treatment.
Thomas Fisher, 22, of no fixed address, admitted the manslaughter by diminished responsibility of Fiona Fisher, 51.
She was found dead from a single stab wound to the chest at her home in Lordswell Lane, Crowborough, in April.
The judge at Lewes Crown Court ordered he serve a minimum of two years before being considered for parole.
Judge Christine Laing QC also said he would remain on licence for the rest of his life.
Fisher - a failing music student who was addicted to drugs and alcohol - was also made the subject of a hospital direction under section 45A of the Mental Health Act.
Fisher was due to stand trial for murder last month but the proceedings were postponed when the prosecution decided to accept his alternative guilty plea to manslaughter by diminished responsibility.
He admitted killing Ms Fisher, a former shop manager for L'Occitane, some time between 25 and 27 April.
Judge described his "bubbly" mother as someone who lived her life "as fully as possible", adding it was "almost unbearable" to read of the family's devastation in victim impact statements.
She said: "For reasons not easy to fathom, for a number of years you held her responsible for the problems in your life."
In a tribute, Ms Fisher's parents and daughter Megan said their "world was torn apart" six months ago and they would never get over the shock of "losing her in such horrific circumstances".
"We would like to put on record that although the recommendation by the Crown Prosecution Service was to accept manslaughter due to diminished responsibility, it was our wish for Tom Fisher to stand trial for murder," they said.
"Our main aim today was to get justice for Fiona.
"She was in the prime of her life and there was no reason why she didn't have many happy years ahead of her."
