Sophia Bush says she's more than ready to move on from rehashing the 'unpleasantries' of her past TV experiences

• Sophia Bush wants to move on from talking about past traumatic experiences on TV sets and focus on the positive.
• That includes her work on CBS' "Good Sam" and her partnership with Lenovo's Work for Humankind.

Sophia Bush is ready to move on from her past traumatic experiences on network TV sets and focus on the many positives in her life.

"I do feel that it's incredibly important to have these conversations," she told Insider when asked about those experiences during a new interview promoting her partnership with Lenovo's Work for Humankind initiative. "I also feel like it's really important to respect myself, my mental health and my own boundaries."

In 2017, Bush was one of many former female "One Tree Hill" cast members who signed a letter published in Variety in support of TV writer Audrey Wauchope detailing the ways women were abused "psychologically and emotionally" by the creator of the teen drama, Mark Schwahn.

Bush also left NBC's police procedural drama "Chicago PD" that year after four seasons playing Erin Lindsay because of assault and behavior she described as "abusive" on Dax Shepard's "Armchair Expert" podcast in December 2018.

"I've given a lot of advice to women and anyone who's in a situation like that," Bush told Insider, redirecting the conversation to her current work on the CBS medical drama "Good Sam," which she called "the best experience" of her life.

"I would so much rather be celebrating that than be continually asked to relive unpleasantries from the past," she added.

Bush has reclaimed 'One Tree Hill' with her former costars

Instead of reliving negative experiences, Bush and her castmates Hilarie Burton and Bethany Joy Lenz are reclaiming "One Tree Hill" with their recap podcast, "Drama Queens" .

The trio rewatches their show, which ran on the WB and then the CW from 2003 to 2012, offering new insight into their characters and behind-the-scenes details. They don't name names or go into too many specifics about their bad experiences on set. Instead, the focus is on their friendship and enduring bond.

"Those girls are my family and we spend so much time together, whether it's on FaceTime or whether we're recording episodes of 'Drama Queens,'" Bush told Insider. "We've forged such a friendship and been able to, as a unit, reclaim so much of what was good and joyful about our first job together while taking out the respective trash.

"And we're just more in love with each other than we've ever been," she added.

The women are also taking steps to be sure that their professional relationship with each other isn't exclusively defined by "One Tree Hill." Lenz and Burton recently filmed guest spots on an episode of Bush's show "Good Sam" in Toronto.

"It was such an out-of-body experience to have those women of this set, but my brain was like, 'wait, what's happening,'" Bush told Insider. She recalled dropping a cue while cameras were rolling because she was so excited to watch Burton and Lenz act with each other again.

Bush is also focusing on her activism and humanitarian work

While Bush has been outspoken about her negative TV experiences in the past, she's geared her career in recent years towards making a positive impact on the world beyond Hollywood sets. She's been an outspoken advocate for sensible gun-control laws, worked with luxury fashion retailer Intermix to encourage voter registration, and previously auctioned off some of her clothes to help fund a school in Guatemala.

Bush's latest venture is a partnership with Lenovo's Work for Humankind initiative.

The program inspires remote workers to use the added flexibility to do good and give back. According to Lenovo, the program provides a select group of specialized volunteers with the tech they need to work remotely on Robinson Crusoe Island, in exchange for volunteer work that supports the local community and helps prevent the extinction of local endangered species.

"To be able to take the idea of work from home and turn it into working for good is something that feels really exciting," Bush told Insider.

"Good Sam" airs Wednesdays at 10 p.m. ET on CBS.
