But I hope that it wont firstly encourage you than disappoint if you dont identify some another reason for your resistance to therapy. Anyway, its important to read it one time.

My best therapist of more than 20 years was also an endocrinologist. She had my DNA tested by a company called Genomind. I suspected that I inherited the chronic depression, and it's right there on paper. They tested me for both my metabolism of a wide range of antidepressant medications, and also for a range of pain medication, as I have terrible arthritis that has limited my activities severely. It's been very valuable to know what will and won't work, and why, and it's helped a great deal with pain management. It was a very sad day when my therapist retired - she was utterly brilliant.
I've had bad and good therapists. You have to do the work no matter who you choose. I think it's good not to make hasty decisions. List some 'test' issues to get some groundwork out of the way with a new therapist. Ethics, religion, politics, anything that you feel could get in the way of your being comfortable and honest - it helps to have common ground. Even if all you do is go to one of the AA meetings that is close to your situation - give it an honest try. We only get one life, and there's always a chance something will change yours for the better.
I wish you luck and success. I gained 20 years from just that one doctor, and I've probably tried 20 others. It's hard, it's a lot of work. But it just might be worth it.
