Unlike a lot of the JW bashing above, here are some helpful suggestions:
The only succesful way (but expensive and a big hassle) is to move away (assuming you don't live in a small town) out of the congregation's territory and do not inform anyone, especially the secretary, of your new location. If you do wish to attend meetings occasionally you can choose a random hall but try not to choose the one that has your residence in its territory so that in the off chance they come to your house in the formal ministry they will not recognize you. With a change of telephone number, preferably unlisted, you will have effectively taken yourself off of the local radar.
Dealing with your family is a more complicated matter.
The only thing I can recommend is to have an honest talk with your mom (other family) and clearly state that they can either have a choice: to let you have your own relationship with (Jehovah) God on your own terms (and that you would appreciate it if they no longer gave you any guilt trips about it--use the you have to "make the truth your own" phrase) OR you can end up DF/DA'd again in which case they will have next to no contact with you so which of these two options would they prefer? (this may get them off of your back)
If you can't move residences for whatever reason, if you have another congregation in your city, you can try "changing" congregations, if you are single you could use the excuse you are looking for a mate or use whatever excuse you want or just don't say anything. In any case if this is the option you go with, do have the new congregation's secretary request your publisher's card, so that officially your old congregation will considered you moved and you will be less likely to be bothered by the old friends. Your new hall might bother you occasionally but most likely as a stranger who comes once in a blue moon you are likely to be overlooked or ignored.
