You recieved good advice from Farkel. Many others here would tell you the same things.
I tell you that the best revenge of all is to lead a very happy and productive life from here out. They never expect that. They wnat you to be as miserable as they are on the inside, if they are good at hiding their misery, that is.
Get into all the things that you could never do before because you were a JW, and that deep down you'd have loved to do. (Not the garbage debased stuff, unless of course, that really is your hearts desire. lol)
You're bitter and angry now and it has it's place, but use those emotions for the good, not for the destruction of self. Use those energizers for moving on and moving on better than any JW would.
I hope that your Mom feels much better physically this morning. It is scary when your parents are ill. Remember though, it was her choice to go, and she was aware of the possible repercusions, and she went anyway. I question why she went. Years ago when my brother was DF and my Mom was younger and in good health, she didn't go and neither did I. Usually the person being DF, or their family don't show up for those announcements. So don't feel guilty for that in any way, if you are.
Wishing you all the best.
