Looking back toward the light with obstacles in the way, creates the impression of threat and danger and doom and gloom. When the clouds are there, the light seems obscured and it feels like you've got walls keeping you from it. It seems like you're trapped in a prison and that everything is against you.
Looking toward the light from a position of being separated from the light, by the clouds, creates the ego. The ego is an attempt to turn around and look back at God and find him blocked from vision as if he doesn't exist. And when the clouds are heavy, it will feel as if God doesn't exist, as if there is no light.
Shifting back into alignment with the source of light, means getting "above the battlefield", through and beyond the clouds, past the illusion of separateness and self importance, and turning around 180-degrees so that you too are a part of the light that shines outward. You need to become a sunbeam, of sorts, extending love outward.
Looking up to the sun with clouds between you is akin to the ego looking inside at itself. The ego wants to catch a glimpse of itself as if it really exists as a separate identity. What you are 'is', and you can't identify it as something separate from you. Yet when you're "under the weather" and trying to wrestle with upsets and darkness you keep trying to look 'at' yourself, similar to how you keep trying to look back at the sun. You don't really need to look at yourself or to look at the source of light, you need to BE IT.
Changing your vantage point changes your perspective. If your vantage point is rooted in your ego then your ego will do the looking and it will look toward the clouds and tell you the clouds are real and that you're separate from God. This will of course be frightening and horrifying. And it's not true, but it will seem true, and you will feel stuck.
Changing your vantage point to that of Holy Spirit (the sun) changes everything. It changes how everything looks to you and what it means. Your light shines ONTO everything you see illuminating it and revealing its beauty and happiness. It helps you to see clearly and fully. It helps you to not be deceived by the strange shadows that play out on the landscape when you are "in the dark". And it helps you to remember there is ALWAYS another way, ALWAYS a better way than any ego viewpoint.
And you need to be reminded... the light of God is always present and always available and always true and always powerful, and no amount of ego or darkness or horror will EVER obliterate it or shut it out or make it permanently lost. EVER. The light is always stronger than the darkness because the darkness is weakness. The light is always there. It is sanity. It is reason. It is truth. Sooner or later you have to admit to it and allow it and accept it and be it. You can prolong suffering but you cannot make it permanent. The light is calling to you to join it and to laugh at the silliness of the ego's mistakes.
God loves you.
