Tuesday may have been harrowing for Pistorius and his family members in court, who also cried, but it must have been so much worse for the family of Reeva who were present.
The judge warned Mr Pistorius that his emotional outbursts will not sway a verdict.
Wednesday he has been giving evidence again, this time describing how Reeva died in his arms.
An altercation between the defence and the prosecution followed as to whether or not Sky News footage of Pistorius at a gun range could be shown. Pistorius remains adamant that he never intended to kill Reeva, or in fact any person.
Describing events following the shooting Sky News reports Oscar told the court Wednesday: "She was sitting with her weight on top of the toilet bowl. I checked to see if she was breathing and she wasn't. "I pulled her weight on to me and I sat there crying for some time. I felt her head on my shoulder and I could feel the blood running down me. "I thought I felt her breathing. I could see her arm was broken. "I was trying to pick Reeva up. I could see she was still breathing. She was struggling to breathe."
"Today, if time allows, he faces cross-examination from prosecuting barrister Gerrie Nel - who is known as the "pit bull" in South Africa. Mr Nel is famed for securing the conviction, for corruption, of the country's former police commissioner, Jackie Selebi. Selebi's defence crumbled during a marathon eight days of cross examination."
How will Pistorius hold up under cross examination? He won't is the conclusion.
Opinion: Much of this case is open to question. If Mr Pistorius did not intend to kill any person why did he shoot four gunshots through a closed door? He may as he claims have believed that a robber was at the other side but in truth he had no idea, unless he knew it was Reeva and her murder was intentional.
It could have been a stray cat or just a vague noise that he had heard. Why didn't he shout a warning and fire a gunshot into the air?
When we act on the spur of the moment strange things can happen, and if you have a gun to hand lethal things can happen.
Mr Pistorius may be an extremely emotional person. It seems strange that more than a year later, after preparing for his trial, he finds it so difficult to keep himself together. But we are all different.
Pistorius, the so-called Blade Runner, has surmounted many challenges in his life which surely mean he is a strong person?
June Steenkamp, Reeva's mother, was not moved at all by Pistorius' tearful outbursts. She remains stony faced throughout the trial but at times covers her face with her hands. She has shown immense strength and dignity, which Oscar appears unable to do.
The trial continues.
