"People see me smiling [and] laughing but don’t see the other times," Kyle Richards said.

Kyle Richards is clarifying some of what went down in the premiere of Season 9 of The Real Housewives of Beverly Hills.

Kyle opened up on Twitter about what was going on in her life during the emotional moment she shared with Lisa Vanderpump at Vanderpump Dogs in the Season 9 premiere (clip above). "I shouldn’t have said that," Kyle tweeted, referring to when she told Lisa during the episode, "I have s--t going on with me, too." "I was referring to the fact that I was dealing with crippling anxiety [and] had to start taking medication for it. NOTHING compared to what Lisa went through."

The RHOBH mom also spoke about how challenging it is to live with anxiety. "Unless you struggle with it it’s hard for people to understand," she tweeted. "People see me smiling [and] laughing but don’t see the other times."

Kyle revealed in her latest blog on Bravotv.com that her anxiety had gotten worse this season because her daughter Sophia Umansky was preparing to leave home for college. "Teddi [Mellencamp Arroyave] comes to visit me at my new home (which I am finally settling into) to workout. We immediately start to laugh about everything. That’s what we do. Yes, of course, I think I’m dying again. I laugh about it, but the truth is my anxiety was through the roof during this time," she wrote. "My daughter Sophia was leaving home for the first time for college in a couple of weeks. If you know me by now, that is very difficult for me. I don’t do well with my children leaving the nest. On top of that, my one eye wasn’t opening all the way, and I had yet to figure out what it was. STAY AWAY FROM WEB MD!"

Kyle recently told Us Weekly and other reporters at the RHOBH Season 9 premiere party on February 12 that exercise has helped her cope with her anxiety. "For me, if I want to feel good and, you know, if I’m stressed, it’s exercise, exercise, exercise,” she said. “So I did my boxing class today, got out all my anxiety. Yesterday was SoulCycle. Tomorrow I’ll be in SoulCycle again.”

Kyle also shared a bit more about how she consoled Lisa following the passing of her brother, Mark Vanderpump, last April in her blog. "In April, Lisa lost her brother. My heart broke for her. She didn’t leave her house for about a month, but we were in constant contact. Once she felt OK enough to go out, we shared a quiet dinner discussing what she was going through," Kyle wrote. "Lisa doesn’t like to show emotion, so I was relieved to hear her open up about it. I think it’s an important part of healing."

In the blog post, Kyle gave more details about that day at Vanderpump Dogs, including the story involving Dorit Kemsley, The Daily Mail party at Tom Tom, and how Teddi fits into it all.
