We here on PC cannot offer mental health diagnoses. Plus I'm not a mental health professional. So I can't tell you whether or not what you're experiencing could be diagnosable as being OCD. For this you would need to see a mental health professional... perhaps a psychologist or a psychiatrist.

However, based on what you wrote, my personal non-professional opinion would be that this does sound like OCD to me. I've struggled with some of these sorts of intrusive thoughts over the years too. And I know how difficult they can be. So if you're not having the opportunity to talk with someone about what you're experiencing, I would encourage you to make arrangements to see someone. Continuing to have these sorts of disturbing thoughts troubling you is a prescription for ongoing unhappiness I fear.

I believe I've replied to at least one of your previous posts. And I usually link members to articles from PC's archives. So if I've already provided you with a link to the article below, please forgive me. However here's a link to an article that talks about OCD & intrusive thoughts:
