Kim Richards opened up about the ongoing drama between her and her younger sister, Kyle Richards, in her latest blog.

Following her appearance at the Real Housewives of Beverly Hills season six reunion, Kim spoke to fans about the ups and downs of her relationship with Kyle, as well as her current sobriety.

"This last year with my sister Kyle was a difficult time, and I missed her a lot," Kim wrote in her Bravo TV blog last week. "It was a rough one, but I am grateful to be where I am today. I want to thank you for all the love and support. The words of encouragement from all of you and the fellow sisters out there were so helpful. Of course Kyle and I had to be ready in our time and do the work ourselves. But it was encouraging to hear about other sisters in our corner. So many thanks to all of you."

Richards also spoke of missing her sister during an interview with PEOPLE Magazine in March.

"I miss my sister," Kim said. "I look at her face today and I want this relationship."

Although Kyle and Kim went through rocky times on The Real Housewives of Beverly Hills and were estranged for several months, Kim hopes to move forward.

"It was very hard. I had a lot of hurt and disappointment. I needed to heal and find a way to move forward," she explained. "Sometimes when you unravel things from the past, it just gets worse. If there is anything boiling, that needs to be talked about 100 percent. But if there are things that are just unsettled, leave them there. There are certain things better left behind."

And despite their frequent feuds, Kim added, "It never meant that I didn't love her and it never meant that I didn't miss her. I've let it go. And I'm happy with our relationship again."
