Mysophobia

Do any of you have mysophobia(germophobia)? If so, how do you deal with it? Lately mine has been getting worse, and every time that I come into contact with anything that isn't preregistered in my mind as 'clean,' I have anxiety/nausea until I can scrub my skin where it came in contact or change my clothes. I've gotten to the point that I am horrified of shaking hands with most people without gloves on(earlier today I was lectured on how unprofessional it is to not shake someone's hand).
