Julia Roberts receives the blame for her half-sister’s death

Julia Robert‘s half sister blamed actress and other family members for her tragic drug overdose in February.

Nancy Motes killed herself at the age of 37 by taking variety of drugs and climbing into the bathtub where she was housesitting.

In her suicide letter obtained by MailOnline, which has been made public for the first time, she claimed that Julia Roberts and her siblings “drove her” into depression.

“My mother and so-called ‘siblings’ get nothing except the memory that they are the ones that drove me into the deepest depression I’ve ever been in,” Motes said in the handwritten note. “I have suffered thru this disease all my life, however It has never been this bad…I burst into tears every morning b/c (because) I woke up.I’ve suffered thru this disease all my life, however it has never been this bad,” wrote estranged sister Nancy Motes, 37. “I burst into tears every morning (because) I woke up.”

Nancy and Julia shared a rough relationship prior to the the suicide. Their relationship fell completely apart last year after she sold a story to a newspaper about how her famous sister used to tease her about her weight.
