It sounds more like depression or another anxiety disorder.

OCD usually is characterized by obsessions and compulsions, and there are different types, one being Pure O, where only the obsessions are present. But it is quite common too. As is the mixed of both obsessions and compulsions.

If you are worried you do have OCD, ask to be assessed. But it doesn't sound too much like OCD to me. But I'm not a professional, just a gal who knows a lot about it and has had it for many years lol. Obviously we can't diagnose you here but a doctor can make that assessment and find out what it was/is.
