Jennifer,
You are who you are on the inside. When I tild my mom 18 years ago the first time I was going to do this, I too felt like it killed her. When I had my name changed then. even though I had it published in a different paper, my mom knew people everywhere, so a friend of hers called her and asked what was that all about, and again I hurt and embarrassed her. Then I left for California and lived as a man for 5 years and she hated every moment of that. Then, I do a 360 degree turn back to being a woman to please her. Got married, had kids and now full circle back to knowing I have always been a man on the inside. Only now my mom is dead, and I had to tell my kids they wont have a physical "mom" anymore, but this is who I am, and I can tell you that I can not change that. I tried, just to please others. Mt point is don't make that mistake. I wasted alot of years always knowing it would come back to me, and one day I would be complete. my top surgery is going to be Aug 7. I could not be happier. You need to do what will make you happy. Think of who and where you want to be in ten years, or even only five, then you will know what to do.
