Bethenny Frankel is feeling "so grateful" as she recovers from an allergic reaction that nearly left her dead. The 48-year-old "The Real Housewives of New York City" star shared her experience in a series of tweets Monday after spending two days in the hospital. "I have rare fish allergy. Sun, I had soup, itched & was unconscious for 15 mins then to ER & ICU for 2 days w BP of 60\/40," Frankel wrote. "I couldn't talk, see, thought I had a stroke & dying & told if 5 mins later I'd be dead." "911 & EPI saved me," she told fans. "I'll never not carry an #epipen @newtonwellesley xo." Frankel was treated at Newton-Wellesley Hospital near Boston, Mass. She credited the hospital and her new boyfriend with saving her life. "He saved my life," the star tweeted in response to a fan who mentioned her new beau. "That is the best hospital I have ever been to and I am so grateful," she added. "The Real Housewives" star said she is "making changes" in her life in light of her rare allergy to non-shellfish. "It'ss very unusual & confusing so I keep it to myself bc it is hard to describe," she explained Tuesday of previously keeping her allergy quiet. People reported in September Frankel is dating real estate developer and film producer Paul Bernon. She was spotted kissing a man who looked like Bernon during an outing in Boston in October.
