Those things COULD happen. And really, couldn't anything happen? Try to think of the most ridiculous thing that could happen. Anything could happen.

I used to struggle with this a lot, and now I only struggle once in a while. It took a LOT of therapy to change my outlook on my fears & cognitive distortions. Medication has helped as well.

Are you currently in therapy, or taking any medications? Talking to somebody about how you're feeling can definitely help.

I'm sorry you are being plagued by these thoughts all day. OCD is a tough monster to fight against.
