Irrational fears...

Okay. I'm afraid of a LOT of stuff, namely chemicals and germs. My most irrational, however, is that I'm afraid to walk on the carpet barefoot in my apartment because I'm concerned chemicals from it being cleaned before move-in (2 months ago) will leach into my blood supply and thus my breast milk, hurting baby. I know it's irrational but it controls me so much! Anyone else experiencing anything similar?
