Yulia Skripal, who was poisoned alongside her father in Salisbury in England last month, has said she has been made aware of offers of help from the Russian Embassy but said: "At the moment I do not wish to avail myself of their services."
In a statement issued on her behalf by London's Metropolitan Police, Ms Skripal said: "I have specially trained officers available to me, who are helping to take care of me and to explain the investigative processes that are being undertaken."
She said she has access to friends and family, adding "I find myself in a totally different life than the ordinary one I left just over a month ago, and I am seeking to come to terms with my prospects, whilst also recovering from this attack on me."
Yulia Skripal, who was discharged from Salisbury District Hospital earlier this week, said: "I have left my father in their care and he is still seriously ill."
She said that: "Most importantly, I am safe and feeling better as time goes by, but I am not yet strong enough to give a full interview to the media, as I one day hope to do.
"Until that time, I want to stress that no one speaks for me, or for my father, but ourselves.
"I thank my cousin Viktoria for her concern for us, but ask that she does not visit me or try to contact me for the time being.
"Her opinions and assertions are not mine and they are not my father's."
Viktoria Skripal has spoken to Russian media about the poisoning.
Meanwhile, the international chemical weapons watchdog is to publish its report into the attack tomorrow, the UK's Foreign Office has said.
A spokesman said the Organisation for the Prohibition of Chemical Weapons has completed its investigation, which it carried out at the invitation of the UK Government.
The spokesman said that, as the requesting state, the UK had asked the watchdog to release an executive summary of its findings at midday tomorrow.
"This transparent and open approach, which we have pursued from the outset, is in sharp contrast to the Russian state's ongoing tactics of obfuscation and distraction," the spokesman said.
