Bobbi Kristina Brown has been in the hospital, under a medically induced coma, for the past several days and new reports claim that doctors are not sure there's anything else left to do for her. According to Fox411, a source close to the family said that doctors told Bobby Brown that the situation doesn't look good.

"It's a matter of when the family wants to let go and accept that she's pretty much not going to make it," the source said. "They've left it up to the family as to how long they want to keep her alive."

The source added that Brown's father is not ready to give up hope and has rallied the family to continue praying that she pulls through. On Monday, CNN reported that the 21-year-old did show signs of a slight improvement when her eyes opened and closed.

However, a source told the site that doctors warned the family not to read too much into it. Shortly after Brown arrived at North Fulton Hospital in Roswell, Ga. doctors placed her in a coma because of swelling on her brain.

Doctors reportedly wanted to remove Brown from the coma earlier this week but decided against it. Until she is fully taken out of the coma, doctors won't know the extent of damage to her brain. Police have said that an investigation was launched into the incident to determine what happened. It was confirmed that drugs were found in Brown's home during a second search of the property but officials have not revealed the type of drug found.

According to Radar Online, Brown's cell phone was also being looked at and a few text messages to a friend could possibly shed light on how she was feeling in the days leading up to the incident.

The site, which released a few of the alleged text messages, reports that it was clear Brown desperately missed her mother, Whitney Houston. Reportedly, while talking to a friend, Brown wrote that the pain still felt "like your heart has been ripped out of your chest."

"I was ALLLL my mother lived for," she wrote. "Despite the fame, the fortune, the power - any and everything, my mother has done FOR ME lady."

"She was and is my everything ma'am," Brown added.
