I REALLY need advice

So this is a long story but I’m freaking out and don’t know what to do and just need advice or something:

So yesterday my mom came home with groceries and told me to put away the meat, so obviously I did. I was looking for more cold stuff in the groceries away from the fridge when she told me to text my sister because she left her phone at Walmart. So since I didn’t find anything else, I went to text my sister and completely forgot to shut the fridge door and just left it WIDE open. I obviously didn’t mean to, I had gotten distracted and it just slipped my mind.

So about 30-40 minutes later the doorbell rang and I saw my teacher at the door. She wanted to come check up on us, which was nice of her. Since our house is a mess I looked into the kitchen to see what mess she was seeing through the door when I noticed the fridge door open. I didn’t think much of it because my Spanish teacher was literally standing at the door so I went to shut it real quick and again didn’t give it much thought.

So like 5 hours later my mom eats leftovers she had in the fridge then like not even 10 minutes after eating them she says her stomach hurts. A few hours later she starts throwing up and continues doing so ALL NIGHT. Like last time she threw up to my knowledge was an hour ago.

That wasn’t my fault right?? I’m so scared that I have her food poisoning because I was being stupid and wasn’t thinking and I feel so guilty and I feel SO bad for her.

The USDA says that food left at room temperature for 2 hours should be thrown out, and this was definitely not 2 hours.

But I can’t help but keep thinking it was all my fault, because what if it was??

I just don’t know what to do.
