Alone,
My experience was somewhat the opposite. I had some of those feelings while I was still "in". Now that I am free, I feel so much better emotionally and mentally., although I felt like I was losing it for about 2 weeks. I would suggest to:
Accept the present.
Don't be upset about the past, since you likely have learned something positive from being a JW.
Vent on this board.
. it helps to keep your sanity.
