I have a problem and can't deal with it help?

ever since i was at school i was bullied by black people especially the girls, I can't stand them i think their rude, without decorum, smell and have an attitude that grinds the hell out of me. I noticed that when i was was on a a packed train i had an east asian man sit nest to me he got of 4 stops later and i was fine, but then a balck woman sat nest to me for 5 hours and i felt myself cringing and getting annoyed by this as time went on, i was fuming by the end of the journey because i absolutely found her foul. how do i stop feeling like this?
