Addicted to sweets/sugar?

I need a way to help me not eat sugary foods. I'm addicted, and I makes me sick to eat as much as I do. I suggested to my mom that we needed to clear the place of all sweets because the temptation is to bad. Buttt, my dad keeps buying cakes and I just can't do it. there's like no healthy food that I like. I really don't want to turn out like him. help....
