Addicted to buenos and getting fat?

HELP! Feb 23rd, I had a baby boy. I weighed 170 and looked incredible. About 2 weeks after he was born, my 10 year old daughter introduced me to Kinder Buenos. Since then- I no longer eat real food. I go through about 10 packs a day (20 servings.) In just a month and a half, I've gained 15 pounds (in all the wrong places.) I feel disgusting, I'm starting to look disgusting. I'm worried I'll end up having a heart attack or giving myself diabetes. Open to all advice.
