The 22-year-old star was in a relationship with the abusive rapper and said she didn't know what to do when it ended.
She said to Marie Claire magazine: 'I was very lost. I have to say I felt really confused. I hate talking about it but it was really crazy because I felt so out of touch with myself and when that happens... It's scary because nothing you say or do feels like it's you.
'You just lose touch of everything that you love and everything that you would normally do; how you would dress or how you would say something... It just feels like it's not coming from you.
'It's just this one empty vase. I felt like an empty vessel.'
