An alcoholic attacked her partner in his own home putting him in hospital for 10 days, Lincoln Crown Court was told.
Kayleigh Heywood was watching television with her partner Darren Seymour when she started shouting and screaming before assaulting him.
Sarah Munro, prosecuting, said “It appears the defendant started to get agitated for some unknown reason.
“She hit him with her fists on a number of occasions.
“She then tried to get him to hit her. He refused so she picked up a wooden bowl and hit him over the head.”
Miss Munro said that Mr Seymour retreated into his bathroom but Heywood followed him and hit him so hard with the bowl that it split. The blow was delivered with such force that she injured her own hand.
Heywood then rang police and said she wanted to kill him.
Officers arrived at the property to find Heywood still agitated and angry. She was trying to hit herself and pulling at her own hair. She was arrested and later told police she was an alcoholic and had been hearing voices.
Mr Seymour was taken to hospital where he was treated for a head injury.
Miss Munro said “He remained in hospital for 10 days. He was in considerable pain and suffering severe headaches.”
Heywood, 30, of Churchill Avenue, Horncastle, admitted a charge of assault occasioning actual bodily harm as a result of the incident on 15 May this year. She was jailed for 21 months and given a restraining order banning her from contacting Mr Seymour for five years.
Neil Sands, defending, said “She has little recollection of what took place because she was drunk. She regrets that it took place.
“Alcohol has proved to be such a destructive influence in her life. Sadly the five months she was spent in custody are the first five months in her life since she was 15 that she has been completely free of alcohol.”
