I was in a similar position as you. Get baptized or get kicked out of the house. I wasn't ready financially or socially to be kicked out of the nest, so I got baptized and honestly tried to give my 100% for Jah and the organization. I only succeeded in delaying the inevitable. There comes a point where you know too much and you can't live with living the lie. It all goes up in flames. But first it has to go up in flames before you can rebuild a more stable, solid foundation for your life.
If I could do it all over again, I would have delayed baptism and and continued to live with my parents while I secretly got my own affairs in order. Then, when I had a few friends and a prospective job I would have moved out. At first, the family would be angry, but since I wouldn't be baptized things would cool down and I could still have a somewhat normal relationship with them. Getting baptized is the first step to losing your entire indoctrinated JW family!
