You're not being selfish & however bad life is for others being miserable ourselves won't change theirs. We lost someone last December, I love Christmas & felt so guilty for still feeling the same joy I always have, his widow picked up on this & told me not to be so daft because all the wailing in the world wouldn't change what had happened. I'm convinced that this crisis is a wake up call for humanity; I'm very eco aware & have to stop myself from getting on my soapbox, however, if it makes me peel potatoes more sparingly, think twice before I buy too much & reduce the amount of stuff I use it will have served a purpose in my life.
