Those people with severe OCD, do you remember if it started after any particular event? And also please tell me how it has affected your productivity at work or education..

You may want to mention the traumatic event if it caused it.

Edit:

I don't exactly remember when it started but a small part of it began when I was 11. My grandparents used to come visit us in the city and stay at home with us from the Village.

I wasn't close to my grandparents, but they used to have this odour that I didn't like plus the hygiene was not there at all.

Sooner or later I started noticing things they touch and how they touch and before touching did she clean her nose with the same hand etc.

I started maintaining hygiene at the next level, washing my hands right after I touched something, and became increasingly conscious about the dirt and germs.. the problems started when the frequency increased a lot to wash my hands and my mind started getting occupied with these unimportant things.

But if you ask me it simply used to drain me down significantly. My studies suffered, critical thinking took a toll etc

Will do the edit more
