Ok, don't laugh.. but I don't know if it's one of not. My room has to be clean ALL the time. I.E. not dust, no dirt, clean sheets, clean closet, vacumed carpet, cleaned desk, all clean.. it has to be clean. I don't know if this is an Illness, but my parents have noticed it because my sister is a pig (not weight wise) when it comes to her room (kinda literally like a pig pin). When ever my friends come over and they dirty my room up, it makes me uneasy.. like butterflys are in my stomache. I'm not annoyed by it, because I like a clean room.. but it's just.. "annoying" at times.
