Lonely, burned out, and depressed: The state of millennials' mental health in 2019

More millennials are also dying "deaths of despair," or deaths related to drugs, alcohol, and suicide, Jamie Ducharme reported for Time in June, citing a report by the public-health groups Trust for America's Health and Well Being Trust.

While these deaths have increased across all ages in the past 10 years, they've increased the most among younger Americans, Ducharme said. They accounted for the deaths of about 36,000 American millennials in 2017 alone, according to the report. Drug overdoses were the most common cause of death.

The report cites a few reasons behind these upticks — young adults are more inclined to engage in risk-taking behaviors, comprise the highest number of enrolled military personnel, and disproportionately live in "high-stress environments" like correctional facilities.

But there are other structural factors at play behind the uptick in "deaths of despair," according to the Trust for America's Health and Well Being Trust — namely the myriad financial problems millennials are facing: student loan debt, healthcare, childcare, and an expensive housing market.

These four costs are part of The Great American Affordability Crisis plaguing millennials that's putting them financially behind.

Studies have found a correlation between indebted people and mental health problems. While this research, by its nature, can't identify causality, the likelihood of having a mental health disorder is three times higher among those with unsecured debt, according to a meta-analysis, or study of studies, in the Clinical Psychology Review. People who have completed suicide are eight times more likely.

While millennials are more likely than previous generations to attend therapy, one in five diagnosed with major depression don't seek treatment, according to the Blue Cross report. That might be due to rising healthcare costs.

Healthcare is one of four key costs plaguing millennials. In 1960, the average annual health-insurance cost per person was $146 — in 2016, it hit $10,345. When adjusted for inflation, that's a nine-fold increase. Costs are expected to increase to $14,944 in 2023.

In fact, more millennials than baby boomers have declined medical or dental treatment because it was too costly, according to an INSIDER and Morning Consult survey.

Millennials don't always have someone to share their mental burdens with — they're less likely to have social support than other generations, as they're marrying later and are less connected to political or religious communities, according to Ducharme.

In fact, YouGov called millennials "the loneliest generation" based on a survey that polled 1,254 US adults. It found that millennials were more likely to feel lonely than previous generations. Of survey respondents, 30% of millennials said they always or often felt lonely, compared with 20% of Gen X and 15% of boomers.

More millennials also reported in the survey that they have no acquaintances, friends, close friends, or best friends.

Cases of burnout have been increasing at an alarming rate in recent years, Ivan De Luce previously reported for Business Insider. The World Health Organization recently classified burnout as a "syndrome," medically legitimizing the condition for the first time.

It's a growing problem in today's workplace because of trends like rising workloads, limited staff and resources, and long hours.

But millennials have reported they suffer from higher rates of burnout than other generations; in a January 2019 BuzzFeed article that went viral, Anne Helen Petersen coined the term the "burnout generation."

Peterson attributed the generational phenomenon to millennials' upbringings, the economic environment they grew up in, social media, and the anxiety of easy, straightforward tasks, like running errands.

Over half of workers say their job is negatively impacting their mental health, according to a new survey from HR company Paychex. What's worse, about 56% of employees rated their company's mental health benefits as either "fair" or "poor."

Many surveyed employees also say they don't get mental health insurance from their job, and 45% of supervisors never received any mental health training.

Paychex surveyed active employees and supervisors using an online survey. The respondents ranged from high-paying industries like medicine and finance to lower-paying industries like retail and manufacturing.

Some workers are more prone to depression than others.

Millennials working outside a full-time, corporate office are particularly vulnerable to depression, according to a University of Exeter review of 28,438 worker reports on mental health. The review found people working irregular hours and the night shift are 33% more likely to develop a mental illness than the general population.

This is especially true for first responders and healthcare workers, who tend to be "on call" during inconvenient hours. A recent Huffington Post article retailed how EMTs and paramedics have higher rights of PTSD, depression, and suicide — conditions that persist even after retirement.

Harassment and bullying at work can also cause mental health problems, according to the World Health Organization, issues that tends to plague female, racial minority, and LGBTQ workers more often.

In a separate study, Kantar, a UK-based data firm, found just over half of workers worldwide don't think their workplace does enough to respond to mental health concerns. Kantar surveyed 18,000 workers in 14 countries.

The lack of resources can even result in discrimination and bias for their mental illness. About 38% of workers said they felt "discriminated against based on their condition," making them the most discriminated workplace group.

In contrast, 26% of workers said they felt discriminated against due to their age, and 12% felt they were discriminated against due to their sexual orientation or identity, the survey found.

That's according to a study conducted by Mind Share Partners, SAP, and Qualtrics and published in the Harvard Business Review found. The study, which looked at mental-health challenges and stigmas in the US workplace, polled 1,500 respondents ages 16 and older working full time.

That was significantly higher than the overall percentage of respondents who said they had left a job for mental-health reasons, 20%. This indicates a "generational shift in awareness," said the authors of the report, Kelly Greenwood, Vivek Bapat, and Mike Maughan.

"Mental health is becoming the next frontier of diversity and inclusion, and employees want their companies to address it," the authors wrote.

Peggy Drexler called millennials "the therapy generation" in an essay for The Wall Street Journal earlier this year. They're cognizant about their mental health, and this awareness is helping to destigmatize therapy.

"Raised by parents who openly went to therapy themselves and who sent their children as well, today's 20- and 30-somethings turn to therapy sooner and with fewer reservations than young people did in previous eras," she wrote.

She cited a 2017 report from the Center for Collegiate Mental Health at Penn State University that found the number of college students seeking help for mental health grew from 2011 to 2016 at five times the rate of new students starting college.

Millennials, she said, see therapy as a form of self-improvement — and they also suffer from a desire to be perfect, leading them to seek help when they feel they haven't met their expectations.
