I'd ask. It's not a secret and your t would be happy to give you information about you, I'm sure. And also, if you think the other dxs make sense, then go ahead and read up on them, and learn about what you can do to help yourself. Also, bring it up to t. I've had many conversations with ts about my dx and none have minded, even when I've told them I thought they were wrong. It leads to good discussions.
