I still do something's now like check the ovens off about 3 times before bed. But I'm glad I over come a lot of it.
One of my biggest issues was cleaning my hands (it all started when I was about 7-8 and I was looking for our class rat and reached my hand under the cupboard and pulled out a headless mouse, the teacher made me scrub my hands so much they hurt) but what helped me overcome this is I developed a love of cars when i was 17 and working on them = dirty. So I got over my dirty hand fear.
Mind you I still won't eat oily foods with my hands including potato chips.
