Yulia Skripal has given her first public statement since being poisoned along with her father in the Salisbury nerve agent attack.
They were found unconscious on a bench on March 4 in the centre of the city.
33-year-old Ms Skripal was in a coma for almost three weeks.
She was discharged from Salisbury District Hospital about five weeks after the incident.
“The fact that a nerve agent was used to do this is shocking” Skripal told Reuters in a statement.
“My life has been turned upside down.
“I woke to the news that we had both been poisoned.
“We are so lucky to have both survived this attempted assassination. Our recovery has been slow and extremely painful."
As I try to come to terms with the devastating changes thrust upon me both physically and emotionally, I take one day at a time and want to help care for my Dad till his full recovery. In the longer term I hope to return home to my country.
Skripal delivered a statement in Russian before providing further written comments in both Russian and English.
She declined to answer any questions.
Skripal also gave more information about her treatment at Salisbury District Hospital.
“I don’t want to describe the details but the clinical treatment was invasive, painful and depressing.
I am grateful to all of the wonderful, kind staff at Salisbury hospital, a place I have become all too familiar with. I also think fondly of those who helped us on the street on the day of the attack.
Her father was discharged from hospital on May 18.
At one point doctors feared both patients could have suffered brain damage but hospital staff said he is no longer in a critical condition.
