The reality star has been sober since March of 2020 (after Season 12 of RHONY concluded shooting). Before that, her drinking was a major topic of discussion on the show, mainly for Ramona. 

When Ramona accused Leah of mixing alcohol with antidepressants, the mom of one stated that it was "repulsive as f--k" to talk about someone else's mental health. She then discussed her past battles for the first time at length on the show.

"I was diagnosed with bipolar II disorder on my 30th birthday, and really dedicated the last seven years of my life to getting it under control and to getting myself to a good place," Leah shared in a confessional on the show. "I'm not even on medication for bipolar II disorder, so for her to even be talking about it in this way is despicable."

That confessional in July of 2020 may have been the first time Leah shared the background of her mental health on the show, but it wasn't the first time she discussed it publicly.

In 2016, Leah opened up in an essay for HypeBae about how it took a while to get answers with regards to her mental health.

She recalled how her therapist initially diagnosed her with clinical depression. Upon reflecting on his text interactions with Leah, the therapist stated that he believed she had bipolar II disorder. 

He put her on medication, which she said turned her into a "zombie." Eventually, she found a treatment that worked for her.

"For a long time I felt sorry for myself that I had to deal with this. It takes up a lot of time. Self-introspection, meditation, doctor appointments, adjusting to meds, getting off meds, AA meetings, etc," she wrote for HypeBae. "It's a full-time job keeping myself mentally healthy."

The streetwear designer was getting herself to a better place, but there was a lot of work to be done to help others understand mental health.

"The stigma around seeking help and admitting a chemical imbalance or emotional and mental issues seems to plague our society," she added.
