Help getting rid of irrational fear

I am 99.9 percent convinced that I am who I've believed I am. Meaning I know I'm an incarnated angel.. nothing else makes sense or clicks the same way... But over the past 3 years I've considered going to a psychic just to see if they could confirm it somehow.. Tell me they see something or whatever. I've never gone because I'm genuinely afraid they will tell me I've been wrong. I don't think I could handle it if I found out I'm crazy or something.. I know it won't change my belief really, but the fear is keeping me from learning. It's holding me back and I know it. Has anyone else felt this fear? How did you deal with it if you did? I know it's not a rational fear, but it's there nonetheless.
