Kinda afraid of a relationship

For starters, I (20M) am single. I want to be in a relationship but I’m scared I’ll end up with some religious nutcase who will try to convert me. What makes it even worse is that I deal with mental health problems (anxiety and ocd). On top of that, the theme of my anxiety is the fear of Hellfire and the supernatural. I am seeing a therapist but I only see them once every other week and the session is only 30-45 minutes; which in my opinion isn’t even enough time. I desire an intimate relationship but I am afraid of ending up with some religious nutty that will only make my anxiety worse.
