The sewing machinist had spent three days trapped in a mountain of rubble surrounded by the stench of more than 1,000 decomposing bodies, reports the Sunday People.
A doctor had found her but the only way she could be freed was to amputate her left arm which was partly crushed under a beam.
The 26-year-old mum said: “The doctor tried to amputate it but couldn’t reach.
"I said, ‘No matter how hard it is, amputate my arm’. He said ‘I’m giving you a saw and you can do it yourself.’
"My head hurt and I was bleeding from my ear. It was horrible. Many of the people around me had died.
"Their blood rolled down my body.
“Everyone was screaming. I was thinking, where is my sister?”
After her rescue Rojina’s worst fears were confirmed. Her sister had died, although another girl was found alive after 17 days.
Rojina’s sister was found by a DNA check on 322 unidentified bodies.
She said: “I never imagined in my entire life that I’d have to see my younger sister’s grave. Never.
“I’d hoped to do a lot of things. What will I hope for now? I have only one hand. I can’t do anything.”
Primark has donated £5million to the survivors and families of the dead who were making its clothes.
They are also giving £1.7million to other workers in the building. Other companies, including Matalan and Bonmarche, are making smaller donations.
