Being told to “just stop”

I have trouble just making it down the stairs in the morning due to my OCD; everything is contaminated and I need to step on the floor is such specific ways to match the pattern of it or something. When my family found out, they did the best they could to help, but there was one motto that they loved: “Just stop.” They tell me to just not do the things that I feel like I need to do, the things that make me feel anything but okay if I don’t do them right. I’ve tried to explain to them that it isn’t really something I can control, but they always shut me down and tell me that “I could stop if I wanted to.” It’s painful to hear that; to hear all of it. I convinced myself that I was faking it all, and that I should “just stop,” and I would insult and berate myself whenever I couldn’t do it. Eventually my family gave up on trying to help, and now my OCD only comes up in arguments.
