119 is just too damn light for a 5'6" woman. Don't you DARE lose weight before talking to a physician! (And if you can't tell your parents your condition, you still have the mental/emotional illness of bulemia.)
At first I thought you were complaining about your "friend;" then I realized you are boasting about what a ****** saint YOU are!
You don't want to put a "strain" on your so-called "friendship." Wake up! Your friendship is already strained to the breakiing point by your so-called "friend."...
