I have OCD too and it is/was no fun at all!
Mine started up after having my second son, Kennedy, born with a Primary Immune Defect. To make a long story short lets just say he was very sick all the time and had to spend weeks and weeks every month in the hospital because he woulkd get "Super Infections" They used reverse Isolation on him, saying that it was people coming into the room and him getting infection upon infection. Well once they found out what was wrong and how to treat him he did not require the hospital stays His IVIG was helping him greatly but I was still freaked out after almost loosing him 2 times to blood infections
So I developed OCD about cleaning things ( sometimes an object would have to be Boiled in cleaning solution, sprayed with a bleach solution and wiped with Lysol before I would let my son even think of touching it) I had raw hands from bleach, and antibacterial soapand other cleaning solutions BUT my kids were never sick and their Peds would ask how I did it. My fears of Germs got real bad when the boy's started school, I had his Immunologist talk with the school nurse and they had a demonstration for his class on how to wash hands and also his classroom got sanitised every night. I even volunteered to come in every other day and wash the educational toy's they had in the class. I had became friends with his Ped Immunologist and it was him who realised that I needed to talk to someone about OCD. I did not think I had a problem at all I just knew I was trying to keep GERMS away from my kids!
