I disagree - my Mom just passed away 2 months ago (today). After telling me many times (while watching Terri's case, and previously) that if she ever ended up like *that* she wanted me to "take her out in a field and shoot her" (her words, not mine) I chose for her, a DNR after the 3rd round of CPR.
There was nothing more I wanted then my Mom to be okay - but she wasnt okay. She wasnt going to BE okay - I gave her the greatest gift I could ever give her, and let her go *home* - To me, keeping someone hanging on for 15!!!! years, for your own selfish reasons, is just that - selfish.
And I also disagree that because they were young, they may have never talked about that. I talk about it - have for years, as did my mom - and watching the Terri case on TV, even my kids (14 & 10) see how asinine it is to have someone there, who is NOT really there.
I would not leave my kids, even though I am a mother, just like you - hooked up to machines for that long, ever. No way, no how. I feel your energy should be focused on THEM, what they need/want/deserve not how youre going to feel with that loss. And keeping 'em all hooked up is all about -you-.
And since it is the 2 month anniversary -
