I’m not going to shut you down. I’m just going to say that when things are truly bad, you need something to cling onto. When hope is crushed, over and over; when the light at the end of the tunnel is in fact an oncoming train that will also kill you if you fail to dodge; when your view on life turns to thoughts like “is it even worth it ?”, in these sorts of situation, realizing that life could in fact be worse, that you have something to be grateful for can be a crucial life-line to someone who thought they had none left.

Is it healthy for a person living under normal circumstance ? Probably not. Is it useful for someone in extremis? From personal anecdote only, I would say so. YMMV.
