A mum-of-two who was left feeling worthless after undergoing lifesaving surgery has died suddenly, prompting tributes to be paid locally.
Sharon Hartman, from Southport, was just 45-years-old when she is believed to have taken her own life on Friday, June 25.
Her daughter Shirley Hartman, 27, said Sharon had battled with addiction in recent years and faced struggles with poor mental health.
Speaking to the ECHO, Shirley said: She has always drank alcohol in a social way but over the years it became an addiction with substance misuse. Her mental health was terrible as well .

With increased use of rechargeable batteries to power modern technology, particularly electric vehicles, researchers have been looking for alternative materials for lithium-ion in rechargeable batteries. Modern batteries use lithium and cobalt, but these have a very limited supply.
Interestingly, the fluoride ion is the mirror opposite of the lithium ion, having the strongest attraction for electrons, which allows it to easily carry out electrochemical reactions.
Researchers in Japan are also testing fluoride-ion batteries as possible replacements for lithium-ion batteries in vehicles. They say these batteries could allow electric vehicles to run 1,000 kilometers (621 miles) on a single charge. However, current fluoride-ion batteries have poor cyclability, which means they tend to degrade rapidly with charge-discharge cycles.
