mom is s*. (has influenza A)

my mom has influenza A. apparently she has been tu, i haven’t heard her THANK GOD but just knowing is enough for me to be anxious rn. yesterday i was going to the bathroom and my bathroom and my parents bathroom are back to back, the toilets being directly behind the wall on both sides. i heard her cough when i was in the bathroom and i immediately freaked out. my heart and stomach DROPPED i immediately finished going to the bathroom and went back to my room. i don’t know for sure is she actually got sick then but now that i know she’s been tu im overthinking that moment. she got s* in the bathroom on the main floor, now i normally don’t really use that bathroom anyways but just knowing she was on the main floor and did that is freaking me tf out. i’m extremely close to tears just thinking abt it rn as i type this. she’s been sick for pretty much a week, she wasn’t tu for the first few days that i know of. i don’t think ill get sick since i started taking vitamin gummies like a month ago and i think they’re helping me stay healthy. but anyways just any advice on how to stay calm and get through this will be greatly appreciated.
