Teddi Mellencamp turned to her fans for advice Thursday as she opened up about struggling with immunotherapy amid her stage four cancer battle.
The former Real Housewives of Beverly Hills star, 44, shared an emotional video on Instagram, showing herself in bed with her shaven head on full display as she detailed the intense effects of the cancer treatment that harnesses the body’s immune system to fight the disease.
'For all of you who have gone through immunotherapy, did you guys have severe anxiety?' she asked. 'Just on random days for no apparent reason? I’m sitting here full of anxiety.'
She continued: 'Is this common? What have you guys done to help make you feel better? Looking for any positive advice.'
She reinforced her concern in the post’s caption: 'For anybody who’s gone through immunotherapy, what did you do to help combat the severe anxiety that takes over sometimes? Or any other advice to help yourself feel a bit better?'
The message comes after Mellencamp revealed she discovered now-estranged husband Edwin Arroyave’s affair with a mutual friend just days before her 2017 debut on The Real Housewives of Beverly Hills.

During a recent appearance on The Jamie Kern Lima Show, Teddi opened up about her marriage, pausing divorce proceedings amid her cancer battle, and admitted her diagnosis felt like ‘payback’ for her own infidelities, which occurred after Edwin’s.
Teddi, who remained on Bravo’s RHOBH until 2020, said the discovery left her ‘broken’ and forced her to beg him to stay.
‘It was with somebody I knew. I mean, I'm not saying that I didn't make huge mistakes, and in my marriage post that, but that broke me,’ she said.
‘That was the first time in my life where I was like, how will I show up every day with a smile on my face and raise these kids, and be this perfect wife and start a television show and become somebody that people like or they think are funny?’
The mother-of-three, who shares Slate, 12, Cruz, 10, and Dove, 5, with Edwin, explained how the betrayal affected her first season on Housewives, forcing her to ‘fake’ her way through filming to protect her kids.
‘People say, ‘Oh you seem kind of quiet or you were kind of passive’—but that’s not really who you are. I wasn’t faking who I was, I was coping. I was so scared that someone was going to find out and ruin my family’s life.’
Teddi filed for divorce from her husband of 13 years on November 1, 2024, citing irreconcilable differences.
She publicly revealed her cancer diagnosis in February 2025, pausing the proceedings.

Despite everything, the pair have maintained a close and amicable co-parenting relationship.
Elsewhere in the interview, Mellencamp finally addressed the alleged affair with her horse trainer, Simon Schroeder, which made headlines in late 2024.
‘I've never talked about it at all, just because of the kids, and I've never wanted anybody to have a guarantee whether it happened or didn't happen,’ she said.
‘But what I can say is, did I do things that hurt other people? Yes.’
As her eyes welled with tears, the reality star reflected on the lingering pain of the situation, without confirming or denying the cheating scandal.
‘To this day, does it still hurt my heart and I wonder if that's why I got cancer? Yes, like it was my payback,’ she said, referencing the cancer battle after her melanoma spread to her brain and lungs.
