I walk with feet going inwards?

i have never really noticed it before but my friends pointed it out,and one of my supposed friends last year said a whole load of horrible stuff about me that i was a freak because i walked with my feet going inwards. Whenever anyones standing near me,they just stare at my feet, and when i was walking home today some boys were tripping me up and said look at the way she walks. this is really getting me down? i mean at least i dont walk with my feet going outwards,anyone tell me how to correct it please?
