Eccentric rapper Danny Brown has sparked fears for his mental health after revealing feelings of depression and suicidal thoughts in a lengthy Twitter.com rant.

The I Will star took to the micro-blogging site on Monday (10Feb14) to take aim at unidentified "fake" friends in the music industry and pour out his feelings of anxiety and his struggles to be accepted by his peers.

He wrote, "I can't sleep my anxiety is at an all time high but don't none of y'all care about that s**t .. Y'all just want me to be goofy...

"F**k u if u was supposed to be my rapper friend and I gotta call ya assistant just to get in touch wit u... F**k all this rap s**t it's fake... N**gas pretend homies not one of these n**gas a come to my funeral...

"Depression is serious y'all think I do drugs cause it's fun... Nobody cares if I live or die .. That's the bottom line .. Y'all want me to overdose just don't be surprised when u get what u asked for... Maybe if I die id get the props i deserved yo u know (sic)".

Brown has since deleted the majority of worrying tweets and instead shared messages of support and encouragement from fans, but he has yet to explain the exact cause of his candid posts.
