Karaan said that, for the past two years, he has tried everything but failed to get over with the death of his beloved woman who "still means the world to him."
"I go out and meet with people, but it only makes me feel worse because she is not there with me," he said. "It becomes even worse when I see a happy couple and remember all our beautiful moments together."
For Samia Doughan, the time seems to have stopped ever since she lost her husband, also the father of their twin daughters, in the explosion.
"They say that the pain of losing a loved one gets easier with time but this is definitely not my case or that of my daughters. We feel worse about this tragedy, especially when Aug. 4 gets closer," said Doughan, whose husband worked at the Beirut Container Terminal Consortium back then.
She cannot forget how she felt at the time when she was anxiously looking for her husband at the port while bodies were recovered from the rubble and her daughters' phone calls kept coming in.
"These moments have become imprinted in my mind, and I just can't get over with them," Doughan told Xinhua in a shaky voice.
"It kills me when my daughters later said they envy me for having lived with both my father and mother until I got married," she said.
Similarly, life has never been easy for William Noun, 29, who lost his brother, a firefighter, in the Beirut explosions.
"Although I still wake up every morning, without my brother by my side, it will never be the same again for the rest of my life," Noun told Xinhua, adding that the sorrow still lingers among his family.
Driven by his painful memory of losing his brother, Noun, along with the families of victims, has been supporting the investigations into the blasts in the hope to bring justice for his brother and all other victims.
"My family lives for this cause now," he said.
Youssef Lahoud, the lawyer who represents around 1,400 victims of the explosions, told Xinhua that the judicial system is determined to investigate the explosions and reach the complete truth, but more time is needed to achieve this goal.
In an apparent message to the victims' families, Lebanese President Michel Aoun on Thursday reiterated his commitment to achieving justice for the victims of the port explosions.
"I assure the families of the victims that I am committed to achieving justice by revealing the complete truth through an impartial judicial process away from any fraud, discretion or injustice, to hold accountable all those who are involved, because no one is above the law," Aoun said on the second anniversary of the tragic explosions.
