Am I being spoiled for making my Mom do this when I'm sick? 15?

No you are not being spoiled it sounds like you may have a serious medical condition. If you can then you should see a doctor. There is nothing wrong with a child being taken care of by her mother when she's sick. I'm sure if your mom was sick you would try to comfort her. I'm 20 years old and going threw a hard pregnancy and my mom comes over to help me when I'm feeling really sick. That's what moms are for.
