Kyle Watts had only been out of prison for a couple of weeks when he complained his mum hadn't made his tea and threatened to smash up her Doncaster home on November 3, 2019.
He left the house and began sending Facebook message which said: "It's your fault I'm small because I didn't eat enough. You need to know this because I will kill you and those around you."
When a relative asked him to delete them, Watts sent her a 14-page tirade of threats, prosecutor Louise Gallagher told Sheffield Crown Court on Friday, September 25.

Watts later returned to his mum’s address, kicked the door and banged on the windows. Before his mother could lock the door he reached in, grabbed her and banged her head against a brick wall.
He pushed her inside onto the stairs, where he put his hands around her neck and banged her head repeatedly against the wall.
"His eyes were glazed and his face was reddened," Ms Gallagher said. "He was totally out of control. She couldn't believe what he was doing to her."
In a statement his mum, who suffers from arthritis, said: "I tried so hard over the years with Kyle. However, I can't cope with him anymore. He threatens and intimidates his way through life."
The court heard he has 18 convictions for 30 offences including violence, threats, harassment and burglary.
He was jailed for four-and-a-half years in December 2017 after he attacked a family "mob-handed” because they reported him for stealing from their car.
When asked about the violent offences he said: "I have done it that many times, it is all through being drunk really."
Dr Kim Fraser said Watts suffers from a personality disorder, which was probably antisocial, and attention deficit hyperactivity disorder (ADHD), but was unsure if there is an underlying psychotic illness.
He recommended a hospital order be made and said: "I believe public safety would best be served by a restriction because of his substantial record of significant violence.”
Edward Moss, mitigating, asked if Watts had made any progress between his two interviews, but Dr Fraser said staff reported “no significant difference in his mental state.”
Mr Moss said Watts is "fully compliant and has no negative thoughts about the restrictions."
"He knows he is in the best place," he said. "He and his mother are slowly rekindling their relationship."
Watts, aged 25, formerly of Balfour Road, Bentley, Doncaster, pleaded guilty to making threats to kill and common assault.
Recorder Keir Monteith QC said Watts admitted having "visions of hurting people" and "was scared of what he might do."
The judge made an order under Section 37 of the Mental Health Act 1983 for him to be detained.
He ordered special restrictions without a time limit for Watts's own wellbeing, and to protect the public from serious harm.
