I'm glad to hear that you're ready to sort things out now. That willingness is essential for the counseling to work; trust and willingness. And yes, you have to build up a relationship with your counselor. You'll know if it's a good "fit" or not. If it's not, after a few visits, feel free to consult another one. You're not tied to one counselor. I went through a few before I found one that I was comfortable with. They are not all the same.
Since you were using cocaine for such a long time, you may benefit from the NA program. Why not check it out? It's a great program for life, and you'll get LOTS of support from people who have been in your shoes and know what you're going through.
There's also a forum, here on SR, for people who are quitting or have quit substances.

This one follows the NA 12 Step program. Though it is not a substitute for face to face support, it is a good addition to it. And you'll certainly get lots of support from people who know what you're dealing with.
I look forward to getting to know you, and wish you the best on your road to recovery.
Shalom!
