You know what you are doing for yourself is right,.. that alone is a great place to be mentally. It looks like you need to figure out how not to feel guilty and to do that I think that you need to find out why you feel guilty so that you can dismantle the things that push you into that feeling of guilt.
You mentioned that you know what you are doing "is right for me" I would take that a step further and say that it is not only right for you, but should be right for everyone. How can leaving a High Control Group ever be the wrong thing to do? Do you think that, even on the slightest level, that there is something right about the WTBTS? I ask because I wonder if you somehow think that you are doing something wrong where the Jws are somehow correct and that you have failed and just could not take it personally.
I think that we need to view it from a different perspective, we need to view the "still in" jws as being in a whirlpool in a rushing river where you have clawed your way out and are now getting your breath and are trying to figure out a way to throw someone a line to help them get out
I think that the only person guilty in that analogy would be if the person who makes their way out just turns and leaves without at least trying to sar some of the others stuck in that whirlpool.
There is no guilt in trying to justify that you made it out of the whirlpool. Don't feel guilty!
If asked now why I had stopped attending I would want to use this one "If you have to ask, then you are not ready to know" or " I guess me BS detector is set to a higher level of sensitivity than most others"
