When I was in my final year as an active, and finally an inactive, Witness, I was very depressed much as you are. Fortunately what kept me going was the belief that somehow God would be able to read my heart and judge me for the good in me.
I would suggest that you READ, READ and READ some more. Posting on this site is the first step. At least you can reach out and speak to others who have gone through the same as you. Don't ever think you are alone, because you are not. We all know what it is like to have gone through the emotions you are going through now.
I am glad that you are moving on with your life, and I hope everything works out for you in your new marriage. And whatever you do, don't feel that Jehovah has condemned you for leaving the "Truth". Many of us have left the organisation, but have not left God.
