(CNN) -- The Williams sisters have not had it easy in recent years. Two of the modern era's most successful women tennis players have been beset by health problems which have deprived the game of two of its most marketable stars.

Serena has overcome life-threatening blood clots on both lungs, while older sibling Venus is this week making her long-awaited WTA Tour comeback as she battles a debilitating illness that has sidelined her since last year's U.S. Open.

After pulling out of her second-round match in New York, Venus revealed she had been diagnosed with Sjogren's syndrome -- an incurable condition which affects energy levels and causes pain in the joints.

"I just didn't feel well before my second-round match, to the point where I couldn't play," the 31-year-old told CNN's Connect the World show.

"At the beginning of the tournament, I wasn't sure how far I would get or what I would do, I was kind of living on a hope and a dream."

After a glittering 18-year professional career which has seen her become the first black woman to be ranked world No. 1 in the Open era, winning seven grand slam singles titles and 12 major doubles crowns alongside Serena, Williams would have been forgiven for deciding to chuck in the towel.

But, instead of eying an early retirement, the winner of three Olympic gold medals set her sights on managing her illness and returning to the baseline ahead of this year's London Games.

"When you don't feel well and things are taken away from you, it's hard to stay positive," the former world No. 1 said. "But, for me, it is not an option to get negative or to feel sorry for myself.

CHAPTER XIII

More than a fortnight had elapsed, but Gordon Wright had not re-appeared, and Bernard suddenly decided that he would leave Baden. He found Mrs. Vivian and her daughter, very opportunely, in the garden of the pleasant, homely Schloss which forms the residence of the Grand Dukes of Baden during their visits to the scene of our narrative, and which, perched upon the hill-side directly above the little town, is surrounded with charming old shrubberies and terraces. To this garden a portion of the public is admitted, and Bernard, who liked the place, had been there more than once. One of the terraces had a high parapet, against which Angela was leaning, looking across the valley. Mrs. Vivian was not at first in sight, but Bernard presently perceived her seated under a tree with Victor Cousin in her hand. As Bernard approached the young girl, Angela, who had not seen him, turned round.

"Don't move," he said. "You were just in the position in which I painted your portrait at Siena."

"Don't speak of that," she answered.

"I have never understood," said Bernard, "why you insist upon ignoring that charming incident."

She resumed for a moment her former position, and stood looking at the opposite hills.

"That 's just how you were--in profile--with your head a little thrown back."

"It was an odious incident!" Angela exclaimed, rapidly changing her attitude.

Bernard was on the point of making a rejoinder, but he thought of Gordon Wright and held his tongue. He presently told her that he intended to leave Baden on the morrow.

(CNN) -- Robert Zimmerman Jr., the brother of the man who shot and killed 17-year-old Trayvon Martin, apologized for his controversial and offensive tweets.

In one, Zimmerman juxtaposed a photograph of Martin with one of 17-year-old De'Marquise Elkins, one of two teenagers charged with killing a baby in Georgia.

Both Elkins and Martin appear to be flipping off the camera.

"A picture speaks a thousand words. Any questions?" the tweet reads.

In another tweet, Zimmerman writes: "Lib media shld ask if what these2 black teens did 2 a woman&baby is the reason ppl think blacks mightB risky."

Speaking on CNN's Piers Morgan Live on Wednesday night, he apologized for the messages, saying they weren't the "right thing to do."

"I realize those were controversial and offensive and I did publicly apologize for them," he said. "I'm a human being. I'm being upfront about what I did. I made a mistake ... Unfortunately (it) may not have helped George."

5 things to know about the case

His brother, George Zimmerman, has been charged with second-degree murder. Zimmerman acknowledged shooting Martin but said it was in self-defense. Attorneys for Martin's family have accused Zimmerman of racially profiling Martin and shooting him "in cold blood."

Robert Zimmerman Jr. said he was trying to make a larger point in his tweets about the "media and their honesty in portraying the person who encountered my brother February 26, 2012.

Letters to Zimmerman show split opinions

"We've been led to believe that it's a junior-high-school-aged person because of the pictures," he said, referring to Martin.
