Am I Lactose Intolerance?

Well every time in the morning I drink milk. When I walking to school my tummy rumbles. At school the farting starts. Every single day I fart. I am really embarred about it because its really stinky no one wants to hang around with me. I take showers and such. Today in math cl I got moved to the front. Everyone was smelling me and such. I cried all through lunch. Please help me am I Lactose Intolerance? If i am that be great cause' i found a cure for my farting problems I think. btw i don't get abdominal pain its just farting after 30 mins - 2 hours of drinking the milk,
