I faded and I sometimes wish I had been DFed instead just to avoid the guilt trips with my parents every time I talk with them. If I was DFed, I wouldn't have to worry about talking with them. If fading is too hard for you, try DF then but keep in mind you will be like a ghost for the rest of your life. You can walk by old friends and they won't even make eye contact with you. Same with your family...you will be treated as if you're dead. Your parents may look through pictures of you and mourn their loss, even though you are alive and well. Just remember that and ask yourself if you can take it.
Whatever you do, don't wait until you're married to a dub and have kids...then it will be nearly impossible to exit.
