Counseling?

For those who have gone I have so many questions. How do you find a family couples counselor? Do they work with insurance? Iv never thought I end up going to therapy but I’m at my breaking point in my marriage and if there’s a chance to salvage it I want to try. It’s not easy being married and maybe most would throw it away I can’t give up so easy it’s worth fighting for. So if you have gone did it help? Anything I should know before starting? Thank you for any advice.
