Quoting inappropriate language in essay?

I submitted an exam essay a few weeks ago writing about ‘Wedding Day’ by Gwendolyn Bennett in Fire Magazine. As this was published in the 1920s, a lot of the views and language is no longer politically correct, including their use of the n word. In my essay, I included a few different quotes which used this word, and I didn’t censor it (I quoted the word rather than saying n**ger or n word). At the time, I didn’t think this would be a problem since I was quoting the source material directly, but now I’m really worried that I’ll be penalised for using this inappropriate language in my essay. Just want to add, the n word isn’t something that I tolerate at all and I never say it. Please help, I’m freaking out!!
