Aitk for asking my friend to study for her tests? Please help me.

Hey guys, genuinely trying to get an understanding. We are in our final year and placements are going on. My friend isn't doing well at all. With a very low cgpa, she can hardly apply to only a few companies. She doesn't even get shortlisted for interviews. The other day, she was crying that she isn't even getting a chance to appear for tests and interviews. She doesn't study and waste time all day watching movies and shows. I am genuinely concerned for her.

On the day of rakshabandhan(saturday), I came back to my room and couldn't find her. (She had 2 company tests on sunday). When she came back at 10, I asked her ki bro didn't you wanna study? Aise to phir interviews ka chance nahi milega. She didn't say much other than it's completely random selection, purely based on luck etc. She said she missed her family so she went out to distract herself. I told her it wasn't based on luck but that I understood that she was sad and let it go(I had even invited her to come to my house as I live an hour away, meanwhile she lives 8 hours awa). We talked normally after that and were playful with each other.

Next day, when we are with one of our other friends, she mentions that I was an asshole for saying that and completely ruined her mood. I told her I had no idea she was even upset over something like that. I had told her it came purely out of concern as I genuinely wanted her to get a job. This caused us to fight, as I kept saying I was worried for her. I had told her previously to maintain her cgpa but she wouldn't listen. She personally attacked my relationship with my boyfriend (we were going through a fight phase recently) and said now she understood why we fought so much, that I was the problem.

Later at night, I tried to initiate contact, saying the same thing. She refused to talk to me and said she is in no mood to talk to me rn and will talk tomorrow. I told her I wasn't dying to talk to her and she can do whatever she wants. A lot of other words were exchanged between us. It has been 2 days since that night. We haven't spoken a word to each other since. We are roommates so this makes things even worse. It feels like she's avoiding me and stays out of the room most of the times. I feel sad that the person I considered as my sister is upset over something so trivial and the silence in our room is hurting me. Aitk here?
