Depth and complexity are not bad things! Is a sense, you're smarter than the GP who "rejected" you because she didn't have enough expertise. Would you have a conversation with Stephen Hawking? No. Why? Because you don't have enough expertise. You can't get very messed up if you're not a creative person with a lot of depth to them. There are "simple" people out there; would you want to be considered one of them? It was a compliment that your GP said she couldn't treat you. So she's an expert on CBT; you are not a "subject" that one can learn about from books or "training."
