As difficult as it is for you now, you're worlds ahead by leaving at such a young age. At least you're not saddled with a jw husband and kids that would be in the middle of you leaving a cult. And a cult is what the Watch Tower is. Google Lifton's criteria of thought reform and the BITE model.
As loving as your boyfriend sounds, he can't be your whole life. It's not healthy for either of you. So live your life. Get a job, go to school, make friends, explore the world! If you're careful about who you choose, you can build a family of very good friends. And if you have non-jw relatives, reach out to them. I'm certain that most of them will be glad to hear that you're out of the cult and will want to get to now you.
There will always be a listening ear on this site. So use it when you need to.
