Doesn't sound like OCD to me. Intrusive thoughts can be with other disorders as well. The voice thing is what stood out to me. For OCD, it's not a voice. It's more like an urge. Like "i have to wash my hands ten times". As opposed to a voice saying, "You must wash your hands ten times." You know? Its kind of a hard distinction sometimes, but what you are describing doesn't sound like OCD at all to me.
