You don't understand, so let me explain.
We thought we'd be able to have children and then we couldn't.
It wasn't a choice to enter into treatments/adoption/donor gametes; it wasn't an option.
Having a child may feel like a choice to you, but it isn't to us.
You and I will need to disagree on that, because you'll never change our feelings about having a family be a need over a want.
When we're cycling--whether we're trying naturally, doing minimally invasive treatments, or doing invasive procedures--I am riding on a roller coaster of emotions.
I am angry. I cry a lot. I am frustrated. I am told one thing and another happens. No one can give me straight answers. No one can make real promises. We pay A LOT of money for the chance to have a child. This money does not guarantee that we will have a child at the end of the day.
