Feeling Suicidal....advice please!!?

Um... So I don't want to wake my parents up... But I had a dream that my ballet tutor told me to kill myself because I'm fat... Already I have been feelin super crappy but this dream didn't help. I know I shouldn't but its so easy because it's night and Boone would hear me sneak out and buy pills.... Please advice.. Also can u post ur email so I could email u.. Only if u want to talk.. Thanks all answers are appreciated
