I understand your situation. My recommendation is a long fade. If you aren't depressed, you can fake it. Depression is one of the only reasons JWs will accept for fading. The sooner you can move out, the better it will be. Letting go of family is hard, and everyone does it to a greater or lesser degree.I've been out over 10 years and am still letting go bit by bit.
I will say though, the more that you disconnect from the JWs and realize how unhealthy it is, the easier it will be to make friends on the outside and to build a real life. It isn't easy, but I can assure you it is worth it and you will be a lot happier. The younger you are when you do it, the better. It's a hard realization at 46 that I have wasted so much of my life trying to please people in a cult. So. Not Worth. It.
You've got lots of support. Do as much as you can without raising too many red flags. But I'd say start planting the "i"m mentally ill" seeds now. It is one of the only ways out.
