Zara Malone was studying English and Classical Literature at Exeter University, the Daily Express reported.
In the last few months of her life, she had become isolated and was drinking heavily, the hearing was told.
Malone's housemate, Francesca Parker, said that on the night before she died, she had found her drunk.
Parker found two bottles of vodka, one empty and one nearly empty, by her friend's body.
The court heard that Malone had depression and was prescribed medication by a doctor.
"She didn't go out and socialise. So I knew she was drinking at home on her own," Parker added.
The coroner recorded a verdict of death by alcohol abuse, adding that Malone was a habitual heavy drinker.
