Im scared

Reading your post I see the word imagined and 100 percent. Those two words can help you. Knowing that your OCD imagination is at play and that it wants you to be 100 percent sure is the game it plays. This is where reality check can help you understand that this is exactly how OCD works.

Read this book "Needing to know for sure" - it may help you.

First, you shouldn't feel guilty about having intrusive OCD thoughts. Over 200 years ago, the English writer Samuel Johnson said/wrote: "We all have thoughts that would shame hell." That means people with OCD and people who don't have OCD. What you're experiencing is an OCD flare up, nothing more. Second, I learned in therapy that it's not the thought's content that's important, it's how you react to it. If you accept it as just a thought, shug, let it go and move on, the thoughts will eventually dissipate. Conversely, if you seek absolute certainty that the thought will never happen you'll on the OCD treadmill all day. Hope this helps.
