Why do i eat when i'm bored?

whenever i am bored or have nothing to do .. i go open my fridge or pantry and grab something to eat. i've been trying to lose weight (i'll give you an idea of what i look like -14 years old, female, 130 pounds, 5'4) but i can't control myself? i don't even know if i'm hungry or not anymore.. it's just whenever i'm bored or need something to do i eat. but my main question is what can i do to get my mind off of food and to not eat while i'm bored... ? please help- any answers are appreciated
