The one that really gets me is "other people are struggling with blah blah blah.., too" and all the variations thereof.
I mean, I don't deny that someone who's, let's say, a quadriple amputee is probably worse off than me, but I didn't make them a quadriple amputee and I can't do anything to remedy their being an amputee, so I can't see why the fact that they have not ended their existence should oblige me to keep on living as well (and really, pointing to somebody who's worse off than me - or anyone of us - and implying that the fact that they're alive means that they WANT to be alive is a logical fallacy ; indeed, pointing to anyone and assuming that because they're alive, it means that they want to be alive is absurd, as e.g. the existence of this message board shows).
