The 'Real Housewives of New York' star is currently dealing with the loss of her on-off boyfriend Dennis Shields - whom she began seeing in 2016 - after he was found dead in his Trump Tower apartment at the age of 51, and has said she's been finding ways to relax her mind by completing water based activities such as ocean swims and beach walks.

She wrote on Twitter: "Doing anything in or by the water is life saving. Beach walks. ocean swims, wakeboarding, clamming, infrared sauna, jacuzzi & my swim really help. When you feel sad, you cry then you just have to force yourself to shift. It's so hard but it works. (sic)"

And after one fan shared a quote with her that detailed how the air near the sea can help "balance levels of serotonin" - a body chemical linked with mood and stress - Bethenny added: "Exactly. I have had trouble breathing and I actually need it. Xo (sic)"

The tweets come after the 47-year-old reality star previously admitted she is finding it "hard to breathe" following the death of Dennis last month.

She tweeted: "It's hard to breathe & I appreciate you giving me the space & support to try to do so. It's excruciating-sudden death is no closure & constant ?s & memories. Our relationship is current so it's painfully raw. Trying to stay healthy & move through it w tears & close friends. Xo (sic)"

Bethenny previously took to Instagram to post a tribute to her late ex-lover.

Posting a picture of Dennis laying on a bed with her beloved dog Cookie - who passed away in October last year at the age of 17 - Bethenny wrote: "Rest In Peace my sweet babies who gave me endless unconditional love. #nowandforever (sic)"

The star was not in a relationship with Dennis at the time of his death, but was left "devastated" by the news.

A source said: "She is devastated. She loved him. He was her family and [her eight-year-old daughter] Bryn's family. Bryn loved him. Dennis was Bethenny's partner, her family, her business partner and her best friend.

"He helped her with things - emotionally and professionally, and he was her confidante. No question that she did love this guy."
