AITAH for my reaction to my gfs situation.

My gf 17F and I 17M are having a rough moment right now. One of her family members is very sick and I’ve been trying to be there for her for the past few days. Today at school she said she didn’t want to see me at lunch which I undertand because she may have just needed space. During last period, she received some bad news about the conditions of their loved one. She told me and my reply was “Oh my god that’s horrible. I’m so sorry _____ (gfs name) . What is ur family gna do?” And then I didn’t get a reply from her for hours. After the period ended I went by her class waiting for her to see her and she didn’t show up. I asked a friend in class and they said that she ended up leaving early. Later it turns out that she went to the bathroom and she couldn’t hold it in and started crying. After a few hours she replys. I keep saying that I’m here for her and that she can talk to me. Later at night, she tells me she was upset at me. She was upset because I didn’t try to see her when she got the news. My thing is that I asked what was going to happen for her family and I never got a reply from her until hours after school and I never knew she even left class. She said she didn’t reply to me because I didn’t ask her to come out and see me instantly. I’m very stuck right now because I know she’s going through such a hard time but I know that I’ve been by her side through these past few days and even the night before this incident I was up after my studying and making sure she was okay. But I just don’t know what I could’ve done, she never replied to me and I didn’t know where she went. AITAH for not seeing her/ for how I replied to her message?
