Are these symptoms of OCD?

Well, back in early 2016 I had something dark happen and it triggered these disturbing intrusive thoughts. Thoughts that something sinister would happen to my characters in stories I’ve written (I’m a writer)

, including children characters if I didn’t do things to save them. I’ll have this urge to run up and down a driveway for example and the number of laps I’d run would build the ‘save’ for my characters. I’d do things like touch something over and over again to rescue them, or thought certain colors and numbers assigned for each character would save them. “If you see something yellow, she’s safe” is an example of my thinking. I started counting and multiplying numbers in my head easily all day to save them, like notebooks filled with numbers I’d perform 

Mathematics with. If I did nothing, I’d have the intrusive fears come and would have severe anxiety attacks.

At some point I was scared of the sky and thought that gravity would suddenly disappear and I’d be sucked up into the sky and onto space where I’d suffocate to death so I’d be afraid an open sky. I’d want to stay in the shade. 

I’d have horrific thoughts of sexual nature that would come and go in seconds but would seriously disturb me, even about Jesus Christ or God. I had to walk away from religion to appease this.

And now I’m having intrusive daydreams about being tortured by insane, psychotic people at a resort I’m staying in easily all day. 

Do you think this is OCD? If so, would do you suggest to cure it?
