Hi Torn in Two. I was a third generation JW that DAed myself when I was 15 because my conscience was bothering me more than I could handle. My family was very hardcore as well so I can relate to you on many levels. I know you feel really lost and confused right now... I did too. However getting out at that age was one of the best decisions I have made in my life. I am now in my late twenties and have known more blessings than I probably could have ever expected to have while inside the organization.
You are indeed very lucky that your family left with you. Giving up the only reality you have known in your life as a teenager is hard enough without dealing with family pressure as well.
Being scared and confused is very natural at this point. It's also natural to be skeptical of and even angry at God. The discomfort is going to last a while, but unlike the discomfort you dealt with as a JW, this is a good kind of discomfort. You've just realized that no one has all the answers and there's no real how-to guide to life so of course you're going to be uncomfortable for a while and not know which way is up and which is down. Eventually though you will start to see the beauty in the freedom that comes with that realization and life will start to look better than you ever imagined it could be because you will realize that the ultimate "truth" lies within you and no one else.
Your personal relationships are going to be topsy turvy for a bit. It's great that you have at least one "worldly" friend that you can confide in and don't have to worry about shunning with. And your JW friends might surprise you one day - I have several from my youth that I am in contact with that are no longer JWs themselves.
I wish you the best of luck on your new journey! Just be patient. It takes time to get all the kinks worked out.
