I know it makes you feel sick.
You're frame your fight as being with "the State" but really your fight is with Reality.
You only accept gestation and birth if it is a "free gift" - so, totally wanted by the mother, and with no complex feelings about it. In fact she can give it straightforwardly.
But actually it's not a "free gift" that your mother gave you. It's a very valuable gift which she gave you at a good deal of cost to herself, her wishes and desires, her body, and her mental health. (I don't doubt there were also many many positives for her, too).
This is the reality although I think it's a painful one for you to face.
It does make you sick to think it - because it makes you feel your dependence and your debt. And whatever your mother was like - it calls for gratitude - which can be a complex emotion to feel.
The reality is no pregnancy is a "gift freely given". Unless they're in denial about it mothers have a greater or lesser degree of ambivalence
It may not be exactly what the mother wanted, but those feelings have to be borne.
There is no magic rule that says no one should ever have to feel no difficult feelings.
The reality is that life is full of them. Having to do something you don't want in the interest of someone else, is one of them.
