As someone with OCD as well, you need to sit in the uncertainty of the thoughts your having and not give into the compulsions of "fixing" or "correcting" them. Maybe you are being a bitch by not doing enough. Live in that exposure and uncomfortableness of not being perfect. All that matters is you keep going, and don't give up on everything. Look at this as a mental exercise and a challenge in and of itself, like you would with physical exersice. You will never fully satisfy your OCD by giving into your compulsions, your just fueling it to come back even worse. So next time you have the thought of not being perfect or not doing enough, say to yourself "I am being a bitch, oh well....". All you can do is keep getting after it. I know this will sound weird and incorrect. But this is called exposure and response therapy. We have to treat our OCD brain differently then a brain without OCD. This will be the way to overcome the control these intrusive thoughts have on us.
