Everyone has great advice so far. Part of your void is because you've had your life planned for you by the WTS. Now it is time for you to plan it. It is YOURS afterall. Look forward to the things you wish to accomplish. This is a journey and won't be solved overnight.
I would also recommend you read Stephen Covey's "The 7 Habits of Highly Effective People" and "First Things First". These will help you look at the whole picture of your life, from your Physical (To Live), Emotional (To Love), Mental (To Learn) and Spiritual (To Leave A Legacy) needs. It is wholistic and it works. This is where I find the WTS fails. They do not have a clue as to what 'True North Principles' are and what the complete and true needs of people are. They have their own agenda and the well-being of their people is not part of it.
