Change in personality? Not much. To me, personality is the surface behaviors that the public sees. I act pretty much the same as ever, though I may be a little more outgoing toward people I used to consider as bird food.
The changes in me go far deeper than personality. I was a cold and judgmental person who believed there are NO GRAY AREAS in the world. Everything could be classified as either right or wrong, Christian or unchristian, for Jehovah or against him.
Now I know that isn't true. There are MANY gray areas and many things that are beyond my ability to classify. I found it quite disconcerting and uncomfortable at first but now I embrace it. I am mentally FREE from the Borg, not simply OUT of the Borg.
