Sorry to hear you are suffering from unwanted intrusive thoughts.
Its a tough thing to deal with. My therapist told me that the more you try to push away the thoughts or try not to think of it, the stronger the thoughts become. I was told that its better to observe the thoughts and try to let it just flow and eventually dissipate instead of fighting it.
As for distractions, I feel they don't offer a long term solution, but they might work to a small extent. Meditation helps a lot, and taking deep breaths.
Or if you have any one you can talk about it to, that helps too
