Bobbi Kristina Brown's boyfriend Nick Gordon has launched a Twitter.com tirade on her family members, friends and fans who have depicted him as the villain of the drama surrounding her near-drowning incident on 31 January (15).

The aspiring actress is still fighting for her life almost four weeks after Gordon found her lifeless and face down in a bath tub at the couple's home in Roswell, Georgia.

Brown's R&B star dad Bobby and other members of her family have banned her boyfriend from visiting her in the hospital, leading to a tense stand-off between Gordon and the clan - and on Wednesday (25Feb15) he took to social media and lashed out at those criticizing him for being partly to blame for the issues that led to his girlfriend's near-drowning.

Angry Gordon tweeted, "F**k all of you with the negatives. I'm going through the roughest time of my life... I'm the reason why my baby is ok!!! End of story."

He later added, "I fight for my baby @REALbkBrown even though my (heart) is full of angry against the world (sic). It's teaching me how to be the person I need to be... I miss her so much I seem so weak right now.

"My heart is full of angry (sic) after the Browns have shut me out they don't even know her. Sabotage... Humans are so phony."

Meanwhile, sources close to the family claim reports suggesting doctors treating Bobbi Kristina have attempted to wake her from the the medically-induced coma she has been in since she was admitted to the hospital are false, and they were simply switching medications in an effort to seek a response from her.
