Unless you've experienced this it can be kind of hard to understand. Everything looks and feels dark. I've got this horrible pit in my stomach and I'm half expecting something bad to happen. I feel like I'm mourning the death of someone close to me, but nobody has passed away. I can't look at my pets without anticipating their death. I feel guilty for no reason. I feel so depressed right now and I don't know what to do. Everything just feels so damn dark.

Has anyone got any advice?
