Scientists claim millions of young people suffer the same issues as suspect in Charlie Kirk murder Tyler Robinson

Tyler Robinson, the man who has been charged in the killing of Charlie Kirk, may have been driven to violence because of his isolation, problems at home and failures in his career, psychologists have suggested to Daily Mail.

Now, concerns have been raised after a new poll showed half of young people in the US are suffering from those same struggles.

Dr Raj Persaud, a psychiatrist in the UK who has not treated Robinson, told this website that Robinson was likely feeling lonely or isolated in his life and there are reports he was in conflict with his family.

Additionally, he had dropped out of college. The straight-A student with a scholarship was now apprenticing as an electrician and spending hours gaming or scrolling online.

The struggles Robinson, 22, allegedly faced are the same millions of others are contending with and mirrors broader trends identified in the survey of more young people saying that loneliness could cause them mental health problems.

A survey from California-based non-profits Hopelab and Data For Progress found 47 percent of people aged 13 to 24 years old — equivalent to 21.6million people — said family issues were having 'a lot' or 'quite a bit' of impact on their mental health.

Having no clear path in life and struggling with school were second on people's lists, both with 44 percent of respondents saying these aspects impacted their mental health.

Loneliness was the third-most cited complication, with 42 percent of respondents reporting this caused a major disruption for their mental health.

Overall, 15 percent of respondents — representing 6.9million people — said they were unhappy in life.

Experts stress that the vast majority of these individuals will not go on to harm others or carry out attacks, but say it is a concerning trend revealing the worsening state of the nation's mental health.

About 61 percent of respondents reported being 'happy.'

The survey, which included 1,300 people, also found that 23 percent of people who identified as members of the LGBTQ+ community reported being unhappy, compared to 13 percent of the cisgender population.

Robinson's sexuality is unclear, but he is reported to have been in a relationship with a transgender individual, transitioning from male to female, who was also his roommate.

He is also from a Republican and religious Mormon family.

Hopelab and Data For Progress said in the report: 'Too many young people report poor mental health and wellbeing, especially in groups that face discrimination and economic disadvantage.

'Throughout the report, young people who don't meet basic expenses, or struggle to do so, report higher rates of key stressors and lower confidence that they'll have the resources and relationships they consider important to their future health and happiness.'

The report is the latest in a grim set of figures highlighting America's spiraling youth mental health crisis, with experts blaming the surge on everything from spending more time on phones and social media to meeting up with friends less often.

Official figures from the CDC also show that among all individuals aged 12 years and over, 40 percent now report feelings of depression compared to 28 percent in 2003.

For the survey, participants were interviewed in July this year, with their responses weighted to account for differences by age group, sex, education, location and sexual orientation.

On their happiness, they were asked to say whether they were 'very happy', 'somewhat happy', 'neither happy nor unhappy', 'somewhat unhappy' or 'very unhappy'.

The survey found that girls and young women are more likely to have poor mental health than boys and young men.

Thirteen percent of surveyed males reported being unhappy, compared to 18 percent of females.

By age group, both 18- to 24-year-olds and 13- to 17-year-olds reported the same levels of feelings of unhappiness, at 16 percent

Asked what was most likely to undermine their mental health, a quarter of participants said family issues and/or loneliness had 'a lot' of drain on their mental health, and 23 percent and 18 percent, respectively, said the two issues had 'quite a bit' of an impact on their mental health.

One in five participants also said that worries about debt, having no clear path, academic pressure, the job market and affording basic necessities had 'a lot' of impact on their mental health.

When asked what would boost their mental health, 46 percent said solo downtown would help 'a lot.'

Spending time with friends was cited as the most helpful among 43 percent of respondents and getting enough sleep was cited by 40 percent.

Hopelab's report concluded: 'The findings underscore that mental health concerns persist — particularly among Queer youth, girls and women, and those facing economic hardship.

'Young people are calling for a fundamental shift in how older generations approach supporting them.

'When asked what older generations are missing, one theme emerged above all others: the need for respect and genuine listening to the needs of young people.'
