Embaressing zit on boob?

i had a small bump on my boob where cleavege is (a v neck would show) and i didnt want it show up when i went to school so i know its disgusting and isnt a good choice but i squeezed it but it didnt do anything. i use this acne cleanser and shower everyday, so i dont effing know where it came from but its so embaressing people will think i dont shower or something. and im seeing the guy i like tomorrow. help?!
