Tameka Raymond has taken to her social network for the first time since her son Kile's jet skiing accident.  Get the updates inside...

After 1 week with 11-year-old son Kile Glover on life support after he was involved in a jet skiing accident on Lake Lanier in Atlanta, Tameka Raymond has asked for prayers via her social network.  She tweeted for the first time since the accident, "#Pray4Kile".  She also changed her Twitter background and avatar to a picture of Kile to garner support.

Her ex-husband Usher has been by her side the entire time.  But since Kile was declared brain dead, it seems there have been no significant changes in his health.  But Tameka has not lost hope.

TMZ reports that Tameka's family is considering taking Kile off of life support as early as the beginning of next month.  Or as long as the insurance company will continue to fund as, reportedly, she will not be able to cover the large hospital bills herself.

According to our sources, Tameka can only keep Kyle on life-support as long as her insurance company agrees to pay ... otherwise she doesn't have the funds to cover the enormous hospital bills.

We're told the insurance company hasn't set a specific deadline, but they've made it clear ... they're only willing to shell out coverage for a couple months ... tops.

Our sources say that Usher -- who helped raise Kyle for several years -- has been incredibly supportive in this difficult time... but has NOT offered to pay for any medical bills. We're told Tameka does not see him as a viable financial option.

Meanwhile, we're keeping Kile in our prayers.
