Paranoid

Is anyone else super paranoid about certain things such as milk water and food? I feel like a weirdo my husband thinks its weird too I will only drink milk if it was bought within 2 days, the water had to be filtered through my brita filter and if it smells weird at all I wont drink it.. If my food has any slight abnornal color like my salad has a little brown on the egde or my fries are not super fresh I wont eat it or my turkey meat is around 2 days old I wont eat it.... I get anxious about it too like almost nervous for some reason.. what is up with this paranoia..
