I have been out for nearly 20 years after having been born into it.
Struggle is an understatement. It took me a few years, lots of mistakes, and some therapy to get my life back together. Untangling my head was the most difficult, realizing it was a load of crap, no Armageddon coming, no judgement took awhile. I used alcohol as a crutch and did many self destructive things.
Life now is great and I am happy. I married a wonderful and supportive "worldly" man 15 years ago. He helped me to have the courage to go to college, I got my degree and it's been all good since then. My job is fulfilling most of the time, my marriage is fantastic, and I have been truly blessed materially. It's not perfect, but I am happy. That has helped my parents to accept me, what can they say?
You are right - once you get it together, it will be better than you can imagine.
