welcome lovedoctor,
Well you've got balls & a brain to give up your hard fought status.
It sounds like you have invested a lot of effort in a community of people. To say goodbye to all that investment and start from scratch is a tough thing to do and may take a lot of time to build up friends outside the WTS.
You won't find a non-religious club that will be the same as being part of a JW congregation. That is because you have built up a lifetime of shared experiences with JW's where you've practiced love-bombing, been a spiritual guide to dozens of people trying to follow a moral code, believed you were doing a life saving preaching work for the creator with Satan as the enemy targeting you, not expecting to grow old but instead living forever. There's no tennis club that can compete with that?!
Instead what you will find after time at a normal club are people who have normal lives who may or may not want a beer after a game of tennis, but won't shun you if you choose to skip a year and come back next season. They won't judge you on how many times you turn up to the club if you get an injury or want to take a vacation. It will take time to get to know people because you won't be seeing them five times a week.
You say you're a people person so I'm sure you will find friends pretty soon. Maybe try and join clubs or do some courses that you may be interested in.
I faded over many years, ensured I was financially independent and had friends outside. By the time I stopped going to meetings there was no real control my family had on me.
welcome again
