Anne told the newspaper she felt email had taken the humanity out of human interaction, and said people were "becoming robots" sat in front of screens.
She described her horror at the rows of ready-made meals on sale in supermarkets, and her fears about the environmental impact of overcrowding and pollution.
"I find myself swimming against the current, and you can't do that," she said. "If you can't join them, get off."
Michael Irwin, the founder of the Society for Old Age Rational Suicide (Soars), helped Anne with her application to Dignitas. He said she had ended her life "with quiet determination", and that her only "regret" was that she had been made to travel to Switzerland, accompanied by her 54-year-old niece, to do so.
Anne killed herself on the 27 March. Just the day before, David Cameron said he would oppose the relaxing of assisted suicide laws in Britain on the grounds that people could feel "unfairly pressurised" into ending their lives.
The Prime Minister intervened when the Liberal Democrat Care Minister, Norman Lamb, claimed that proposed legislation to legalise the practice among terminally ill adults with less than six months to live had achieved "quite widespread public support".
Assisted suicide remains a criminal offence in England and Wales, technically punishable by up to 14 years in prison - though Crown Prosecution Service guidelines indicate anyone acting with compassion to fulfil a dying person's wishes is unlikely to face criminal charges.
