I think it's fair and natural to occasionally let the darkness that exists in this world get to you. Because it's real. And because you're real and you're noticing and experiencing all this evil (because I don't know another word for some of these people), so it would be, I think, either impossible or delusional to always keep 100% optimistic. There's a half of the glass that's very dark and f-d up. But yes, all the more reason to work on healing ourselves and helping others - which you do, with your beautiful energy, every day, Eric. :)
