Taylor Armstrong: I developed a drinking problem after Russell's suicide

Taylor Armstrong has nothing to hide. In the Feb. 25 episode of Bravo's "The Real Housewives of Beverly Hills," Kim Richards asked her sister, Kyle Richards, to assist her in confronting the widowed reality star about a presumed drinking problem.

Armstrong, 41, took the sisters' advice to heart and thanked them for their support. The "Hiding From Reality" author elaborated on the episode -- and shared many more dark secrets -- in her official Bravo blog on Feb. 26.

"I went through about nine months where I was drinking to cope with the pain and the memories. I was drinking to forget, to stop the recurring images in my head, to relax enough to try to sleep at night," wrote Armstrong, whose estranged husband, Russell, committed suicide in August 2011. "I quickly discovered that one glass of wine made it a little easier, two would help me forget, three, four -- you get the point."

Armstrong continued, "I was self-medicating, and the sad truth is that I didn't know another way to get through the days -- and nights. I was confronted with the truth that the life I thought I had was only an illusion. What I finally realized was that 'pain waits for you.' I would medicate for a day and the next morning all the emotions would come flooding back -- not to mention the massive headache."

"Thankfully," Armstrong wrote, "I had an amazing support system, and they helped me realize that it was time for me to feel my emotions and let the healing begin."

The reality star and mom to 6-year-old Kennedy added that former child star Richards "is no Dr. Drew" and wasn't in a position to be doling out advice. "She doesn't spend enough time with me to be evaluating anything about my life," Armstrong wrote of the "Escape to Witch Mountain" star, who completed her third stint in rehab in January 2012. Regardless, she praised her friend's recovery. "I care for her, and am deeply happy that she is having success with her sobriety, finally."

Armstrong also apologized to new cast member Yolanda Foster, with whom she butted heads in earlier episodes. "When she and I met, I was in a bad place. I was in no state of mind to be making new friends," Armstrong said of the Dutch model. "I was watching my life fall apart, and looking at her perfect life wasn't helping. I was convinced that I would never love or trust another man again, and here she had two successful marriages and a beautiful family."
