Ms Mitchell, who has diabetes and hypertension, said her partner appeared to be recovering from Covid-related pneumonia while she became seriously ill.
She said paramedics who attended her at home on 2 July were called back 10 minutes later when her 19-year-old son found Mr Lawrenson dead in bed.
She said: “Les made a terrible mistake and he’s paid the ultimate price for that.”
Ms Mitchell was admitted to hospital the same day and spent a week on a Covid ward.
She said she felt foolish for putting her daughter and older son at risk when they came to help to care for the couple’s 11-year-old son.
Daughter Carla Hodges, 35, said: “[Leslie] was so brainwashed by the stuff that he was seeing on YouTube and social media.
“He said: ‘A lot of people will die more from having the vaccine than getting Covid.'”
Ms Mitchell said she would be having the vaccine as soon as doctors declared her fit enough.
