Your vent helps many realize that they are not alone. Some other posters have made good suggestions. I like Gill's. You can expose certain aspects of the WTS Corporation. Many of us would like for you to exploit it. Being an active elder gives you some access and leverage.
Just don't get involved too much procedure-wise. It will sap your energy. We know that you are mentally out. If you believe in God and Jesus, just treat your fellow members in the congregation as Christ would. Keep the dangerous fanatical Pharisee like ones away from you. You don't need them. You can still be a refreshing person to all you know, at home, work and in the neighborhood.
When I find that many people who are frustrated and depressed about being a JW is when they are following men and men's rules/traditions. No wonder why Jesus felt sorry for the people who were under the yoke of the religious leaders of that time.
To feel better, exercise some. It does a world of good.
