I had to separate myself completely from family for a while in order to heal. Changing the language is a good suggestion - stop calling it "the truth"! I enrolled in university, which really helped. It was also helpful to embrace many customs that were forbidden - celebrate xmas, birthdays, mothers day, etc. I joined a political party and became active in union events, the first time I voted was a real rush! I learned the words to the national anthem and proudly stood up and sang at first opportunity. It may seem insignificant, but every little thing you do that was denied you as a JW is another small step towards becoming whole again.
And don't forget the importance of educating yourself regarding doctrine & practice. The more you learn about how wrong these things were, the easier it is and the better you feel.
