Want to control obsessive thoughts

I've relapsed today and this is causing my OCD to get out of control. When I did a 26 day streak which is my longest in past 5 years, i got my OCD problem under control. But ever since I relapsed, i have been on a binge which is causing my OCD to get worse. Moreover I'm thinking that this is the last time I'm going to relapse and my mind is like " no!. You need to relapse one more time." And this goes on. I've been making these patterns which i know are nonsense, but I do it again. Also can anyone tell me how can i overcome fear of numbers 3, 6 and 7 and all the numbers which contain these numbers. I need help badly and I'll be very grateful for your help.
Thankyou.

 

I've been told in my childhood by my friends and some relatives that 3 is not a lucky number. That 3 causes things to go wrong. I don't know how I developed negative feelings for 6 and 7, maybe coz 6 is 3+3. And about 7, i just don't know why i started to get anxious about 7. The weird thing is I know that getting worried about these numbers is bulls**t. But my mind doesn't help me.
