my grandmother died 20 years ago to the date yesterday. i had to make the decision to unplug her. she was braindead for a week. we did, and i remembered she told me if she was like that, to pull the plug, so i did.i understand you, maybe you thought you shouldn't have done it, but the person is better off now, they are not sufferring or just existing.you did the right thing. i hope you feel better about it soon.
