Drowning in the Dark

Do you know what it's like to drown? No, I don't mean literally. Well, anyway, here's my take: You can drown in many things, whether it’s water, thoughts, burdens, etc.. But, if you can see a light at the end of the tunnel, that means you have hope. What if you don't have hope, though? What if there's not a way to escape? I guess, then, you're just left drowning in the dark.
