Frustrated

So my little sister (14) was up all night in the bathroom puking and having diarrhea she ended up having to make a pallet and sleep in there she took one sip of Gatorade to take medicine and a few minutes later puked it up

I was also up taking care of her my mom came home from work the next morning she asked my aunt to take her to the hospital to which she replied "I'm too tired not right now I've been up all night" like bitch when you were asleep well before anyone else so we ended up calling 911 because after all night of puking plus waking up and puking she needed to go and we don't have a car of our own

After they left my aunt and cousin were bitching because she went??? Saying they went threw it and she should've just toughed it out when my cousin also went to the hospital for the same thing like really??? You're gonna bitch for a 14 year old going to the hospital for not being able to keep anything down?? Do I not have a right to be mad??? when I took up for her their excuse were "I went threw jt for 9 days and I was fine" really??? No you did not I fucking live with you pretty sure id know if you couldn't eat for 9 days

Update: she's still at the hospital and getting fluids, zofran, and toradal
