I would say that before you can "rebuild" you, you need to find you! So many of us subjugated our interest and feelings to the borg for so long that we don't even know who we are, much less what we want out of life... Some sign up for classes at universities or colleges, some check out other churches some take up hobbies and sports...
What you don't hear about (or at least often) is the person who drops out of classes due to depression or lack of interest or the person that joins another religion thats only another cult in "sheeps clothing" or the people that get very into drugs and alcohol...
Take it slow, make sure that your doing what you WANT to do not just having a reaction to freedom! If you want to go back to school/church/bar/cricket team/etc... make sure that you go for what you WANT and make sure that your reasons are genuine! Never be afraid of self evaluation! You've already done the largest most painfull self check that (hopefully) you ever will so from here out it should be easier!
Is your wife joining you on this quest? I understand that can make it easier!
And read CoC it really will help!
