Sandra Webster, 62, is friends with Dorothy Heathcote, 96, one of the residents at the home.
She said she was helping her to find alternative accommodation because Mrs Heathcote “doesn’t have any family living locally”.
“It’s like the wind has been knocked out of her sails,” added Mrs Webster.
“To leave her home in the first place was a big upheaval for her, to leave her family memories.
“But then she thought she had found her forever home, so I am concerned about her when she moves.”
Claire Bateman, who used to work at the home, started the petition objecting to its closure.
Before the threat to its future was announced, it had 27 residents, but now there are six people there.
“I am certain that if they (the Salvation Army) changed their minds and decided to keep the home open, most of the residents who had moved would be coming back in a heartbeat,” she said.
