It's true I've ben very fortunate myself, but I've also met quite a few people who didn't have the chances that you yourself had and still managed. So I don't believe you "haven't been allowed to have children", I feel like you've encountered a local minima and just settled yourself in it.

It's fine with me, I'm not here to tell you how to live your life, but I wanted to convey that something else is possible for you, you aren't hopeless.
