No, you won't act on them. What's going on is this: You have anxiety. The intrusive thoughts cause anxiety and fear. The bother you and you want them gone desperately. But the more you try to eliminate them, the longer they end up using your mind as their habitat. They stay for much longer. The solution is to just realize that it's your anxiety playing tricks on you. The fear that you will act out on them -- again, anxiety. So replace those thoughts with, "It's my OCD making me think this." Instead of fighting the thoughts, analyzing them, trying to get rid of them, and so on and so forth, you have to neutralize them. Make them meaningless. And that's what they are -- nothing but random thoughts created by your anxiety.
If you fear panic attacks, most likely you'll continue to have them. If you fear intrusive thoughts, most likely you'll continue to have them. Same thing. So stop placing so much value on these intrusive thoughts and see them for what they are, just meaningless thoughts your anxiety came up with in order to bug you. It's a jab. You want to fight back? Ignore it. Be more like Gandhi and less like Tyson. That's how you beat OCD. Just accept them and let them sit in your mind while you realize that it's JUST anxiety. Convert the fear to something like this, "It's anxiety making me fearful. If I didn't have OCD I wouldn't be fearful." And it's true. People without OCD get the same intrusive thoughts, but it doesn't bother them. So the thoughts go away on their own. When you have OCD, you hold on to them and start feeling fearful, guilty, etc. That's the opposite of what should be happening. It proves you're a good person that you're obsessing about this. Bottom line -- you wouldn't be ruminating about it if you didn't care.
