The only POC in a white work space

I am 27 year old woman living in Denmark. I am of Danish and west central African origin. I currently work at a workplace where I am the only POC, I am also the youngest. All of my co-workers are white women aged 45-64. I feel very isolated and lonely when I am at work, I feel like their tone is often very harsh but is not personal against me, they are like that with everybody, but it is still hard to be in everyday. It also switches up, sometimes they are nice and it is also not always what they say, but how they say it. Today my co-worker was talking about a teddy that one of our patients came in with that was extremely dirty. She said it almost looked like a neger (Danish word for the n-word) because it had become so dark. Then she was like "whoopsie, we can't say that anymore, it was just really dark like you my name. In Denmark there isn't the same culture like in the US, and Danes doesn't view a lot of things like racism, they just think it is nice chit chat. I didn't know what to say, but I really hate to be here. I want to start a master's degree in September, but even just 7 months (minus 3 weeks vacation in the summer) more here is a lot. I was thinking about quitting before though so I don't have to be here in August and just work as a substitute different places for one month. But this is the things I deal with daily.

Her comment today comparing my skin to a dirty puppet pissed me off, she is calling me a n-word but she has never asked me about my roots, I am at the verge of the tears often going to and coming from work.
