How do I get help for my OCD?

For the past several years, I've had a wide array of irrational fears, doubts, and compulsions. I've also suffered two nervous breakdowns as a result. My parents have put me on this all-natural antidepressant that has worked well to an extent, but is still a far cry from true relief. Sometimes the stress can be overwhelming, and it makes everyday activities excruciating. I have seen a doctor about this and he told my dad that the stress was just something the average teenager goes through. He was certainly no help at all. I told my Dad afterward that I thought I might have GAD. I'm not sure if he got the message. Both my parents have brought up OCD and putting me on an all-natural anxiety medication, (they are very wary of chemically-based medication), but until a few months ago, nothing has really been done about it, because I didn't want to bother them. But eventually, I was able to finally open up to them and tell them that I thought I had some symptoms of OCD. Then my mom eventually batted around the idea of seeing this educational specialist we both knew for some CBT, which she also conducts. But I really don't want to open up to this woman about my most personal problems; I'm too familiar with her. My mom is also a devout Christian and she only wants a Christian therapist for some reason, but I'd rather have someone who can listen to me objectively and help me from an unbiased viewpoint. What path should I seek now?
