Hello,
Great for posting your feelings and thoughts it really helps.

It sounds like you have some troubles within your life and mind right now.

They sound as if you are distressed about the changes in your logical, mental, and general thought process.

From what you've written which I am sure is just a snippet. I would not say you're really exhibiting OCD.

What's happening is you're doubting your faith, this happens to all religious people from time to time, consciously or subconsciously.

I used to be a belieber in God and Jesus. These days I tend not to be at all.

When you doubt your faith in anything, if it's God or even a trust in a friend, doubt yourself or many other things for that matter it could be anything.

It could cause you to feel distressed, maybe anxious.
I'm afraid there's not much you can do medically apart from medication.

That all depends on the doctor you see, and how much they think anxiety and distress is effecting your life.

This is just my opinion nothing else.

I hope you feel good soon, and your mind allows you some rest and relief about what you do or don't think, believe or choose anymore.

Take Care
J
