The heartbroken family of Peaches Geldof are desperately trying to understand her tragic state of mind in the final weeks before her death, reports the Sunday People.

Those who were closest to the presenter fear she was still struggling with her “dark side” after previous drug problems.

They now face the agony of learning if there was any truth to their concerns when the results of toxicology reports on the 25-year-old journalist are returned in the coming weeks.

The Sunday People has also learned that friends of Peaches say her 20-month-long marriage to ­musician Tom Cohen, 23, may have hit temporary problems as she battled with her conscience over being a working mother of two.

The friends have told how bread-winner Peaches felt pressure to earn money to support the family but also wanted to be at home with her sons, 23-month-old Astala and 11-month-old Phaedra.

She had told friends she wanted to move back to London from the idyllic country house she bought two years ago to see more of them and her relatives.

Peaches, who died suddenly at her Kent home last Monday, was unhappy over her relationship with father Sir Bob, 62.

Friends say the pair were no longer as close as they once were .

She had complained to members of her closest circle that the former Boomtown Rats singer wasn’t as involved with her youngest son as she had hoped.

One friend said: “Whenever Peaches was in trouble, she self-medicated because that was what she had done all her life.

"She really tried not to but this was just part of who Peaches was.

“She was very complicated. She ­desperately wanted to be a certain type of girl with a perfect life and a perfect family.

"But things just aren’t like that.

“Peaches had a dark side. Everyone knew that, including her family who have been through hell with her drug problems over the past decade.

“In the last few weeks she seemed overwhelmed. She always kept a lot of plates spinning with her work and ­finances.

“She was the main bread-winner and that put her under a lot of strain.

“She also felt incredibly lonely. She was once so excited at moving to the Kent countryside where she remembers her early childhood for being so happy.

“But recently she wanted to return to London. She wanted to be nearer to her sisters and her friends.”

Police investigating Peaches’ death at her five-bedroom home in Wrotham used sniffer dogs. Forensics officers also searched the £1million property.

A postmortem was carried out on Wednesday but the coroner said her death remained unexplained and he adjourned the inquest for a toxicology report.

Peaches’ body was released on Friday and the family are now making plans for her funeral.

But as they do so, they are still trying to understand the events leading up to Peaches’ death.

Friends say that she may have begun indulging in drugs once again.

Just days before her death her former nanny Anita Debney – one of the few constant features in her life – posted an anti-drugs video on her Facebook page.

The film featured a young mother who had taken drugs on a bus.

Friends are speculating that Anita, who was known to the Geldof family as “Ninor”, could have put it on the social media site as a warning to Peaches. She and Peaches were particularly close .

Anita cared for her and sisters Fifi-Trixibelle, now 31, Pixie, 26, and Tiger Lily, 17, when their mother Paula Yates, 41, died of a heroin overdose in 2000.

Peaches was treated by paramedics for a suspected drugs overdose in 2008 in London when she stopped breathing for several minutes.

She refused to go to hospital in case her father found out.

She later admitted taking drugs, saying: “It’s something people go through in their lives, especially ­growing up in London.”

She headed off to Los Angeles where she experimented with drugs and the Scientology “religion”.

On her return to Britain she moved in with her ex-nanny.

Sir Bob was ­increasingly concerned about her welfare but shortly after his pleas, she met Tom and became pregnant with Astala before marrying.

It appears others were also worried about Peaches’ health.

An American TV presenter who goes under the name of Jonny Makeup told how he believed she may still have been struggling to steer clear of drugs.

Makeup, 30 – real name Jon Szymanski – said: “Being a recovering addict myself, I know she struggled to be and stay clean.

"I don’t know if this had ­anything to do with her death. I just hope she was at peace.”

Friends say the strain of wanting to create the perfect family environment which Peaches didn’t have following her parents’ divorce led to problems in her own marriage.

One told how she felt under pressure to earn money, but she also missed being with her children all day.

She was a follower of “attachment parenting” – a belief in never letting children out of sight.

The friend said: “Peaches felt under pressure to earn all the money from writing and doing television but at the same time she wanted to be at home with the kids all day.”

Another family associate told how Peaches wanted her home to be beautiful but Tom struggled financially.

The associate said: “Things were tough. Peaches loved beautiful clothes and homewares.

"There was some ­exasperation between the two of them.”

Last year Tom split from his indie band S.C.U.M which had a cult following.

He and Peaches, along with his sister Holly, had made plans to set up a lifestyle and vintage shop in north London’s hip area The Cross but it never materialised .

Another issue that made Peaches sad was the isolation she felt from her dad.

Peaches would regularly put pictures of her children with their paternal ­grandfather Keith Cohen online but never any with Sir Bob.

In an interview published this week, Peaches was asked why the Band Aid charity hero was not on any of her Instagram photos with the kids.

She replied: “He doesn’t see them. It really is his loss to be honest. Thank God for Tom’s parents who are totally amazing.”
