Farting, is it a problem for me?

I've been farting WAY too much. I do try to hold it in but all i end up is having diareah. I've gotten into trouble for this in school, and also, I try to explain to my teachers and friends but they ignore me. And Im not turning into cl clown. I saw 8 to 14 kids wearing Gas Masks. What Should I do?!?!?
