Meet The Teenage Girl Who Is Allergic to Almost Everything is a good story about the blood disease I have (MCAS, or Mast Cell Activation Syndrome). I’m very fortunate that I didn’t have bad symptoms until the last 7-10 years or so, and removing part of my colon recently has also helped reduced the symptoms. It would major-league suck to have this disease when you’re 15 years old.
