i think i overcame ocd by doing exactly what you just said i had it very strong 5 years ago and i just fought it i still have some rituals now to do sometimes but its ok it happens once in a while i would say not even one everyday and its pretty much a random cycle i think you dont have to fight it too hard its a mistake you need to understand how to live with it first so not getting upset or feel stupid when you have to get up to touch the doorbell 4 times or it causes anxiety and discomfort then you can resist some rituals sometimes and keep on in this way its not your enemy its part of you and you will never beat it just learn to live well with it dont treat it as a problem
