Los Angeles, July 16 Singer Usher's ex-wife Tameka Raymond will soon be forced to take off her 11-year-old son Kyle Glover from the life support system as the insurance coverage is about to expire.

However, Raymond seems to have not lost hope, and keeps telling her friends that she believes in miracles, even though Glover has been declared brain dead by doctors.

According to sources, Raymond can only keep Kyle on life-support as long as her insurance company agrees to pay, otherwise she does not have the funds to cover the enormous hospital bills, reports tmz.com.

Usher has been supportive and has stood by Raymond in the tough times but is not providing financial support or paying medical bills.

Glover was struck in the head by a jet ski on Lake Lanier earlier this month and doctors declared him brain dead a few days later.
