"I'm not asking for your charity or anybody else's," Wilson said. "I'm just asking to be treated equal."
She is fighting for a loan modification.
"I want to know why they won't take my money because we do qualify for a loan," Wilson said.
Wilson says she and her husband fell behind on the mortgage when she was diagnosed with cancer. She has made unsuccessful attempts to negotiate a permanent loan modification with the bank.
Wells Fargo says the family hasn't made a mortgage payment since 2008.
"Wells Fargo Home Mortgage has decided to proceed with the eviction of James and Ana Casas-Wilson given all retention options have been exhausted," the bank said in a statement. "We provided loan modifications on two occasions, and both offers were declined. We also have offered financial relocation assistance to help transition them to a new residence. Those offers were turned down."
Wilson was given notice that she could be evicted on Tuesday night. Supporters from the Alliance of Californians for Community Empowerment have joined the fight.
Wilson went to the sheriff's department to appeal for authorities not to enforce the eviction. In a letter, her doctor says her cancer is terminal, and moving could impact her condition.
"Do you think that I want to go through this every year, every six months?" Wilson said.
Supporters say they're appealing to the South Gate City Council for help, and they plan to start a 24-hour vigil at the home.
