I agree with what most have said here, research the Watchtower society, research the history of the organization, learn as much as you can. The more I learned, the less I feared. The more I learned, the weaker the hold they have, and eventually it's gone.
There are many who have dealt with, and are currently dealing with family. There are many who have been able to keep their relationships with those still in. Those would be the ones I would focus on. There is a whole stream of "how leaving the watchtower affected me" on youtube. Many have great advice re: family, moving on, etc.
I also suggest freeminds.org. They have a phone/email help line set up. I was able to call and talk to someone, that was very helpful.
Hang in there, keep reading, keep talking, like has been said...it does get better, it does get easier, freedom does come.
