Life circumstances can sometimes cause you to feel like you're buried under a pile of dirt. An optimistic perspective of the dirt is that the you're not buried, but planted. When you're planted preparation is being done to breakthrough the dirt to bloom. However, while in the ground it is dark but the darkness is not all bad.
Darkness is normally known for being scary because it is hard to see what is around you. It feels lonely and empty. You are never alone in the dark. God is always there. He is your light during this time.
In the times when it is just you and God, that’s when it is the best time to be intimate with Him. You can really focus in on God when everything around you is dark because He is the light. For example, when going to a movie theater, the lights are up during the previews but as soon as it is time for the feature presentation, it is completely dark except for the screen. Why? It’s so everyone can focus on the movie and the distractions are removed. The darkness hides the distractions and allows the audience to zoom in on the movie. This is how it is spiritually, the darkness in your life means that it is time for you to zoom in and completely focus on God, who is the light. The Bible says in John 1:5, NIV, "The light shines in the darkness, and the darkness has not overcome it."
God's light can not be put it out by the darkness you are surrounded by. The only time it can stop shining is when you turn it off, just like turning off the movie in a dark room. The only way for the movie to stop shining is to turn it off so it can no be seen. The same thing with God's light, if you don't read the Bible, pray, worship, and find ways to spend time with His light, you will not be able to hear from Him. You will be ignoring Him and won't be able to see His light. His voice will be spiritually turned off from you.
Turn on God's light in your darkness. Be intimate with Him, when you feel like you are buried in darkness. Remember you aren't really buried but planted. Get rooted in Him.
