My GF(21F) is angry at me(23M) for not reminding her to order food.

Hi redditors, So something happened and need your advice on the situation. So me and my girlfriend have together for quite a while now everything was well, we have had our normal ups and downs nothing much, but today was something different. So my girlfriend is a student and lives in college campus, hence if needs she to order food she had to do it before 9PM.

Now she orders food often as she dislikes hostel food and i am the one to usually remind her to have food/order food. So today I was feeling a bit low(took a day off from work too as I had bombed an interview) hence I was sleeping all day. We were talking all day in between but around 6-6:30 i slept again and woke up at around 8:10, and then called my girlfriend initially she did not pick up( I assumed she was sleeping too as she was mentioning how sleepy and tired she was feeling). After 15 mins she calls back and then snaps at me for not reminding her to order food, I told her I am sorry but I was sleeping hence I could not but she was not ready to listen and kept saying go and sleep now no need to talk and all it was like she was making me feel guilty just for sleeping. Then after sometime she says that she was hungry hence she needed to vent hence she lashed out at me. I literally kept saying sorry to her just for something as natural as sleeping. Then said that she just wanted to vent and she outted on me and then she wanted me to apologise to her. I am really not understanding what I did wrong here apart from the thing that I couldn't remind her to order food but that was also due to because inwas sleeping.

At this point I am reconsidering everything in our relationship, is this normal and was I really in the wrong ? Please give me some advice.
