Okay so not only did my niece have a severe kidney infection, but she also had pneumonia the doctors found out after doing some more tests. She hasn't been eating well my mom said at the hospital... but after finally eating a (melted) slushie and some McDonald's (urgh, wished she would've eaten something a little more healthy while at the hospital...not ragging on fast food in general, it's just that when I saw her she looked like she was on the verge of death....). But anyway, she's allowed to come home today now!
This was all very scary, but I'm glad she's healthy enough to leave. Now I can finally focus on homework (joy) without anxiety.
