Two parents who tragically lost their daughter when she jumped from a bridge in London last year are preparing to walk 135km to raise funds in her memory.

Anna Sargent a former BBC press officer and Manchester Metropolitan University graduate suffered with depression throughout her teenage years, and in later life became an alcoholic.

Last year, as part of her quest to find a cure for her depression she discovered Baclofen, a prescription-only medication use to treat the symptoms of multiple sclerosis which some claim can help alcoholism.

Anna became dependent on the powerful drug and was admitted to a rehabilitation clinic for treatment following an overdose on September 9, 2013, but disappeared on September 18 after being transferred to Charing Cross Hospital.

She was found on the shore of the River Thames eight days later after the side effects of withdrawing from the drug including hallucinations, insomnia and confusion, led her to sadly take her own life.

Nearly a year on, Margaret and David Sargent, from Sandhurst, have raised over £5,000 on a page set up on charity Mind’s website to help others suffering from similar problems. They are now preparing to tackle a walk in the Cotswolds to continue fundraising.

Margaret, 65, said: “The memory page was set up so that anyone who wanted to donate a gift or flowers for Anna’s funeral could give to the charity instead. It still continues to receive generous contributions.

“Now David and I will walk to raise more money. Walking is good for the body and mind, so we felt it was an appropriate task.

"Anna, suffered from complex mental health issues which overwhelmed her, now David and I want to help challenge the stigma of mental health" - Margaret Sargent

“Every donation means a great amount to us. Anna, suffered from complex mental health issues which overwhelmed her, now David and I want to help challenge the stigma of mental health.”

The Sargents had an original goal of £2,500 and have surpassed it meaning Mind will be able to provide training and work experience for people with mental health problems.

They are now aiming for £3,000, with the additional £500 helping to run the Mind legal advice line.

They decided to walk the 135km, which will take them nine days, as it is the combined total of their ages.

Margaret regularly helps at the Sevenoaks Mind branch with fundraising and events.

She added: “The Sevenoaks branch is fantastic they do so much good work and I always like to help as much as I can.”
