Why is life so cruel?

So yesterday i come home to find out that nobody told me that my 4 week old niece was rushed to the hospital early that morning. Apparently they didn't want me freaking out and getting into an accident or skipping school. They didn't keep her which is good i guess, but she has been projectile vomiting and just screaming in pain. She had an ultrasound done, i found out when i got home. I immediately stopped doing all homework and went to my sister's house. Leah was fuzzy but she finally fell asleep on me as i watched her for my sister while she talked to the doctor and our mom. The doctor said Leah's ultrasound was abnormal and she was having pyloric spams. For those of you who don't know what the pyloric is, its a sphinctor at the bottom of your stomach that opens and lets the partially digested food go into the intestines to be digested further. Well Leah's is spazing and barely lets any food through, hence the vomiting and obviously its causing her a lot of pain. She has to see a specialist this friday and they think, THINK that they can treat this with medicine. If not, she will need surgery. SURGERY! and she is only a month old!!! It's not fair, and its horrible to see my sister cry and Leah in so much pain.
