A lot of people are suicidal because they have severe generational trauma that they're afraid they'll inflict on their potential friends, partners and kids, and therefore be terrible persons. That's NOT a good reason to kill yourself.
A lot of people identify as trans because they have severe sexual trauma that made them disconnect from man/womanhood and therefore feel like terrible men/women. That's NOT a good reason to transition.
I get what you're trying to say. But this girl is actively mourning her potential children and writing poetry about imagining their smiles, while feeling so toxic she cannot imagine having them. Worst case is she gets sterilised, THEN processes the trauma, then regrets it. Best case is she processes the trauma, then comes to a conclusion (whatever that may be), then lives a life less filled with fear (child free or not).
Also I want to stress this: there is nothing wrong about talking to a therapist.
