You start to appreciate how wrong it all is when you realise you are unable to speak to your friends and family about what is so important to you, knowing that in an instant they can all be taken away from you.
I found it to be an extreme relief when I was d/f. But I would not recommend you d/a, at least not straight away. For your own emotional well being, it is better to take time to think things through and build up a new social group and new friends not related to the Watchtower. Before being d/f I spent a couple of years making new friends and it made such a difference having them to lean on through through the bad times. You will quickly find that there are many "worldly people" that are just as loving as Witnesses, and their friendship is not contingent on labels such as religion.
