HELP!!! Where can i hide food from my family to get out of eating?

Okay so i don't eat that much, It makes me feel like ****, My aunt is down and she's leaving tomorrow and she's making me pancakes tonight, Dreading that, and i don't eat in my room so if i say "Hey i'm gonna eat in my room" They will get suspicious, So what can i do?? Please help me, And if i have to eat it, I will throw it up, The problem is i can't throw up, I tried everything, My fingers,Toothbrush, I don't know if the salt water thing works though, How can i hide and do all of this? And i have two huge dogs, so they will be happy to take my food and i don't have zip locks under my bed to put the food in, what's a good substitute? And i'm 13 and if i do hide the food under my bed, Where will i put it later? Thanks. and respond fast, Thanks again!
