Dsis has just told me she has been making herself vomit in order to control her weight. She was v upset and begged me not to tell anybody esp DM.
I don't want to ignore her cry for help despite having had some issues recently with dsis/dm that led me to see them a lot less.
I know she begged me to not tell DM but should I tell her anyway as Dm is the one who lives with dsis and I feel she should be aware (dsis has other health problems).
What is the best thing to do?
