The fireworks finale of Bravo’s “The Real Housewives of Beverly Hills” — a near-violent fight between sisters Kyle and Kim Richards — is still sending off sparks.

In an unusually personal blog posted over the weekend, Kyle now says the fight — which sent sister Kim into rehab — left her with “anxiety and panic attacks.”

“First off, let me say, I love my sister so much,” she wrote in the blog, posted on Bravo’s Web site.

“Sometimes I wish I loved her a little less. You may be thinking, ‘You have a funny way of showing it.’ And you’re not wrong.

“After this horrible argument between Kim and I, we didn’t speak for a long time,” Kyle wrote.

“My heart was broken, and I suffered an incredible amount of anxiety and panic attacks. Next to losing my mother, this was the most difficult time of my life.

“I wish we were just characters on television, but this is all too real,” she wrote.

“Throughout the season, I have come across as angry toward my sister. At times, it seemed unwarranted. I know that. I know how bad it looked. The truth is, I was angry. There were problems brewing between my sister and me off camera.”

The unexpected fight between the sisters — who are, incidentally, aunts of debutante Paris Hilton — rocked the final episode last week of the soapy “Real Housewives” series’ latest edition.
