While many thought Taylor's performance of her tune Innocent at this year's MTV Video Music Awards was unnecessary, the 20-year-old felt she had to do it.
She told NYMag.com: 'I think a lot of people expected me to write a song about [West], but, for me, it was important to write a song to him.'
Although the Mine singer said she wasn't interested in people feeling sorry for her.
Swift added: 'It doesn't really add anything good if I start victimising myself and complaining about things because I'm proud of that performance at the VMAs last year, where my fans helped me get through it.
'And there was a lot that went down backstage that I will always be thankful for, and the fans in the subway know exactly what happened that night... I feel everything, I've never had this thick skin that can't be... It's not like I am bulletproof in any sense of the word.'
Kanye, 33, sabotaged Taylor's acceptance speech at last year's VMAs when he snatched the microphone off her and said she didn't deserve to win.
