Kesha was sexually, physically, verbally and emotionally abused for 10 years by her producer, Dr. Luke, to the point she nearly died.

According to a new lawsuit -- obtained by TMZ -- Kesha claims Dr. Luke was abusive towards her almost from the get-go -- when she signed on with him at 18 -- and made repeated sexual advances toward her. She claims he would force her to use drugs and alcohol to remove her defenses.

In one instance, Kesha claims he forced her to snort something before getting on a plane … and during the trip he force himself on her while she was drugged.

On another occasion, Kesha claims after forcing her to drink with him, Dr. Luke gave her what he called "sober pills." Kesha claims she woke up the following afternoon, naked in Dr. Luke's bed, sore, sick … and with no memory of how she got there.

Kesha also says there was physical abuse ... once she says he attacked her at his Malibu house where he was "violently thrashing his arms at her." She says she escaped and ran barefoot down PCH and hid in the mountains.

Kesha's lawyer, Mark Geragos, tells TMZ, "This lawsuit is a wholehearted effort by Kesha to regain control of her music career and her personal freedom after suffering for ten years as a victim of mental manipulation, emotional abuse and an instance of sexual assault at the hands of Dr. Luke."

Wouldn't be surprised if it was true Dr Luke is human Garbage
