I venture a guess that the reason why you're feeling good is because you're now...
1- In control of your own destiny.
2- Not attending a place 5 times per week where they subliminally feed you that nothing and no one is good enough, therefore, you must give more, more, more!
3- No longer concerned with only having friends for as long as you're a JW; even then those friends would look down on you if you're not doing exactly what the WBTS says.
4-Being true to yourself.
