My roommate uses me as a courier

Her lazy ass never goes to university and just lays in bed 24/7. When I’m at uni, she always texts me things like, "Buy [something] when you come back, I sent you money," and I always reply with, "Okay, okay." Today, I was getting ready to go to a restaurant to eat, and she said, "Where are you going? Can you buy me a pregnancy test?" I told her I couldn’t because the restaurant was close, but the pharmacy was so far away. She said, "Okay," and I felt relieved. But when I was eating and having fun with my friends, she texted me again, "Please, please buy me a pregnancy test, I feel shitty. Pharmacy will be closed after 20 minutes." IT’S NOT MY FAULT THAT YOU HOOK UP WITH YOUR BOYFRIEND FIVE TIMES A DAY! WHY DO I HAVE TO BE THE ONE BUYING YOU PREGNANCY TESTS?! I feel so embarrassed every time I have to buy them. I’m even a minor, when I come back to the dorm, everyone just stares at me 😭. This is the third time I’ve had to buy a test for her. I’m in another country, and I really don’t want to argue or fight with anyone especially not with my friends because I already feel alone here. On top of that, everyone here is racist, and it’s really hard for me.

Anyway, have a good day! I just wanted to write this down and let it out to feel better🥲.
