Forcing a minor to have a child/become a mother is a different issue altogether. That is a totally different argument and both sides have positions on that.
Forcing a minor to “get well” so she can live is another issue. Once she’s an adult, she can take her own life if she wishes…heck, she could do that now if she wanted! (not that I want her to!)
Seriously, if she wants to die, then she can just commit suicide NOW. (again…that would not be what I would want.)
