I have a problem with saying racial slurs

ever since I was 3 I had a fascination towards words i can't say. when i first got my computer and the first thing i did was look up was bad words. i then came across ethnic slurs and i have been saying them to this very day. i was suspended from my school for calling my math teacher a "negro." when i got out of college i was fired multiple times for calling the customers slurs such as cracker, negro, chink, wetback, and many more. i am currently out of a job right now due to my love of racial slurs.
