Your story it is very common amongst JW's. There are hundreds of thousands stories like yours. Once you find out the truth about the 'truth', then you cannot stay and pretend.
You can see my previous posts as (justhuman)and you will see that there are people with worst situation like yours. When I left I had a family and children. 10 years have gone and I managed to make a new life, new friends. I was 33 when I left and 39 when I was disfellowshiped.
I enjoy my freedom, and I made my choices regarding religion. So you are young, you are not commited with anyone, you have no children. It is good idea to move into another town, become innactive, make new friends and plan your life according to your will.
I don't suggest you to be disfellowshiped. Like that you will lose all your family bonds. Even if you move to a new town try to avoid to join a JW's congregation. You will save your self from the 'elders' that will call and ask why you don't go to the meetings
