With his father suffering haematoma, Jeffrey's talks with Ballymena were put on hold while he rushed to comfort both of his parents.
"When visiting relatives in England, my poor father fell down 12 stairs and had to go to hospital," said Jeffrey.
"He was most unwell but of course as always he was asking me how I was doing.
"I obviously had talked to both dad and my mum about the Ballymena job.
"From his hospital bed when I was leaving his last words to me were 'go and get it sorted out'. His words were very clear to me."
Jeffrey added: "All significant family members were consulted and the job was discussed with everyone. I got full backing from everybody which I really appreciated."
That included his sons Gareth and Thomas, who used to travel to Linfield games as children when their dad was in charge at Windsor Park. Now adults, their dad admitted that the conversation with them about making a return to Irish League management was a serious one.
"Gareth and Thomas were very supportive," said Jeffrey.
"Their questions were probably more exacting than anyone else's and gave me great clarity to think why wouldn't I return and work as Ballymena United's manager," he added.
When Jeffrey makes his comeback, football fans across the country will see a slimmer person prowling the touchline than before.
He revealed: "That is about listening to my doctor and having the time to get my health and wellbeing sorted out.
"Even now that I am going back into management I intend to keep that going."
