Paisley, who is due to get married on Sunday, was struck down with the virus after returning from a holiday to Ibiza with friends in July.
Just two days after returning home, on July 18, he began to feel unwell before testing positive for the virus two days later following a PCR test.
By Friday, the fit and healthy 30-year-old was suffering from breathing difficulties and went into hospita l but chose to return home where his condition rapidly deteriorated.
Speaking to the Daily Record, he said: "I went to Ibiza, which was on the green list, with two mates. When I came home I didn't feel very well and got tested, which I had to do anyway."I tested positive and from there I just plummeted.
