In dark, there is light.
"The people that walked in darkness have seen a great light: they that dwell in the land of the shadow of death, upon them hath the light shined." Isaiah 9:2. You are cared for.
In fear, there is hope.
"Be strong and of a good courage; be not afraid, neither be thou dismayed: for the Lord thy God is with thee whithersoever thou goest." Joshua 1:9. You are never alone.
Sometimes life is like shifting sands. You will never be one thing forever. Your mood will change. Your perspective will change. Your circumstances will change. Sometimes you will be happy and sometimes you will be sad. Sometimes you will soar, and sometimes life will be rough. But try to remember that all of this will shift. So when sometimes you can't see past a haze, just remember that it's just a haze caused by events or even chemicals . . . and it, too, will shift. I don't mean to say that things will get better; I mean that things will shift to a different angle and then back and then to a new place and then back again.
Sometimes remembering that is all we can do until we're ready to start moving back into positivity.
"Light House" by The Word Alive can start to set the stage, start working you in. And then "My Lighthouse" by Rend Collective brings your focus back to what the light really does mean, to what stays constant through the shifting scenes.
