- [Isabella] At 17, Tabitha Grandolfo moved from Hong Kong to Providence, Rhode Island, to study at Brown University.

- It was 2021, and the COVID restrictions meant that if I wanted to go home, I would have to spend three weeks in a hotel in quarantine before I was able to, like, go back and see my family.

- [Isabella] Living far from home, she began feeling depressed and lonely, and she was having trouble making friends.

- I was in a play.

And I was really excited, it was my first, like, play that I did on campus.

A roommate and a friend came to see it, and I came back after the show and, like, they didn't talk about it at all.

And then the two of them went to some, like, party or after party and left me in the dorm alone.

I was just sitting there in my room alone, folding laundry.

- [Isabella] By the time she returned to Hong Kong at the end of freshman year, her depression had become overwhelming.

- I remember, like, not being able to get out of bed, and my mom was like, "Do you think you can go back?"

- [Isabella] Stories like Grandolfo's are all too familiar to psychologist and Harvard lecturer Richard Weissbourd.

- When people think of loneliness, they often think of senior citizens.

But in our data, the people who have the highest rates of loneliness are young adults.

They're people in their 20s and they're people in their 30s.

- Weissbourd conducted a national survey on loneliness during the pandemic and found that one in three Americans felt miserable levels of loneliness.

For young adults, the numbers were even higher.

About 60% felt that way.

Those statistics have improved since that time but remain a worry.

What particular challenges do young adults face that you feel contributes to this high rate of loneliness?

- People don't feel a sense of community at work, they don't feel identity or purpose in work that they once did.

There's much less participation in religion among young people.

And religious communities are places where you're asked to think about your responsibility for people in your community.

We're much less likely to reach out to people who are lonely or to create the kinds of communities where everyone feels a sense of belonging.

- [Isabella] In 2023, the U.S. surgeon general warned that there was an epidemic of loneliness.

- And social disconnection is associated with an increased risk of not only depression, anxiety, and suicide, but also heart disease, dementia, stroke, and premature death.

- Loneliness is just as deadly as smoking an entire pack of cigarettes a day.

- [Isabella] Ashley Kirsner has spent much of her career studying the psychology of loneliness.

- One of the trickiest things about loneliness is that the lonelier you are, the more negatively you see social situations and therefore the less likely you are to put yourself in social situations.

- [Isabella] Kirsner saw firsthand how damaging this mindset can be.

For two years, she volunteered at a suicide hotline in Boston, where she began to notice a pattern among the people who called in.

- No matter who I was talking to, they generally had someone who cared about them in their life.

But when I asked them, "Oh, have you talked about how you're feeling to that person?"

almost across the board, people would say, "Oh, no, we just don't talk about that sort of thing," or, "No, I don't wanna be a burden."

It just seemed like the determining factor of whether you were lonely or not was whether you felt comfortable opening up to those people.

I started asking, "Well, if the roles were reversed, would you want them to tell you about it?"

And the answer was, without exception, "Oh, of course I would want them to tell me about it."

So I realized there was this weird gap between how vulnerable people were comfortable being and how vulnerable people wanted others to be with them.

- [Isabella] It gave her an idea.

She created an event she called Skip the Small Talk, where people could get together and practice being vulnerable.

- Before I knew it, we sold out at 50 tickets weeks in advance.

It was supposed to be a three-hour-long event.

I had to kick people out after seven hours 'cause they wouldn't stop talking to each other.

(people chattering) - [Isabella] Skip the Small Talk has since spread to more than 20 cities across the country.

- All right, you got about 30 seconds left.

30 seconds.

- I remember one thing people expressed at the event were, "Oh, I thought I was the only one who wanted to talk about this more vulnerable, deep stuff."

And people were surprised to see that other people wanted to talk about it too.

- [Isabella] Talking about it was also important for Brown student Tabitha Grandolfo.

She worked with a therapist, took medication for her depression, and opened up to a friend.

- I told her, I was like, "I don't know how I'm feeling, I'm feeling really nervous."

And I was telling her, like, all the reasons why, and she was like, "We can create a routine together."

- [Isabella] Each morning, she and her friend would eat breakfast and then walk to class together.

And each evening, they came together to do homework.

- Thanks for coming.

- [Isabella] She also got involved with a mental health advocacy group called Active Minds.

- The first day I joined, they're like, "We're looking for someone to do our graphic design," and I was like, "I'll do it."

- [Isabella] The group has a tradition of making friendship bracelets.

- Everyone, have their eyes closed.

- [Isabella] Each bead that's shared represents a positive quality the giver sees in the recipient.

- Oh my God!

- [Isabella] Grandolfo has kept her bracelets from years past.

- I have some others too, but this one, I feel like, is special 'cause it's the first one that I did.

- [Isabella] They're a reminder of the community she's found.

- No matter what happens, I can go on a Wednesday evening and be able to see these people who are willing to, like, listen to me.

- [Isabella] Grandolfo is now a senior and plans to graduate this spring with degrees in psychology and theater.
