Foot problem ( repost urgent help!)?

Ok this is a long story. Last week my sister came home and was really tired and asked me for a foot mage. I didnt want to but i did cuz shes my siser and i love her. Well my friends came over and rang the doorbell to ask if i wanted to hang out. They noticed what i was doing and now at school everyone bugs me thinking i have a foot ! i like this girl and i think she likes me because she has been wearing sandals, and heels and getting pedicures now that she found out. Feet are gross and i dont know what to do!!!! this could become a sitcom!
