Phoebe,
Please reread your last couple sentences over and over again. They have almost complete control over you because you are too scared to do anything! I am not judging you, I have been in your shoes. Take the time that you need to take.
Please know this.... When you DA, you are making a clean, purposeful break. You are in no uncertain terms advising them that they have no control of you whatsoever and you do not wish to be associated with them.
You can sit in your house and be afraid. Cross the street when a jw walks by or look at the ground when you see one in the store but what kind of life is that??? I know its difficult but the feeling of taking back your power, pride and dignity is something that does not happen often in life. It is LIFE-CHANGING!!
Good luck and godspeed.
