Leaving isn't easy.
What I think is important to remember though is that although you lose the social life of the hall, you didn't really have deep friendships there anyway. (at least I didn't...and the one person I was friends with kept in touch with me even when I faded).
You will certainly miss the hall and everything it entails, including the social contact. However it is possible to rebuild your life and it need not take that long.
I was married when I left and my husband left me not long after. I found myself without the JWs and without a husband! Overall it has shaped me into who I am today.
I'd much, much rather be away from that cult than be in it. It is a cult...there is lots of information which shows exactly how they use the tactics and control methods. Free yourself while you are still young!
