Do you hide your OCD?

I literally do everything possible to hide the fact I have OCD from my friends and the people I know. I will suffer exposures when out with friends silently, then spend hours scrubbing myself raw when I come home. I always have to make excuses as to why we can't do things at my house - but it's really I can't let them contaminate my only safe space. My parents fucking ridiculed, yelled at, belittled my OCD for small things, like literally just asking them to wash their hands during COVID. How can I expect a stranger to accept me when my own family couldn't?
