I used to have really bad OCD. like not you're usual Haha I Hate Germs And Everything Must Be Organised. Guess I Must Have OCD xD but the full blown condition, and it did consume my life and was actually depressing
I'm not even going to go into some of the **** that I used to do, but it wasn't anything like having a fear of odd things (like the images in the OP) and I wasn't afraid of germs (although I did used to wash my hands to the point they were cracked and bleeding). I didn't tell my parents as they wouldn't understand and I was too embarrassed to tell any of my siblings. I went to my GP for about a month but I was too embarrassed with that too so stopped going altogether
This began when I was like 13 and got worse and worse, until I was around 15 and decided to put an end to it once and for all, and eventually out of sheer motivation with no help from anyone I became completely OCD-free
