"surpass and survive"
- I think this is the story of your life @Belle.
"Do you see your genes dictating who you are?"
- that question is so awesome I can't even begin to answer it at short notice.
Your genes dictate your framework, your nurture dictates what you do with it.
Its like a house...your genes say "You are a two story colonial", your nurture then adds what neighborhood that house is in, etc.
I know not a thing about the subject but good luck dealing with all of this stuff you sound like a courageous woman and I hope it all works out well for you x
Thats hard core Belle.
How was the meeting with them? Were they delighted to see you? Where they polite/gracious hosts? Did you meet both your mother/father? Did they give you the impression they want to keep a relationship with you? Do you want that? What did the whole experience feel like?
