Do you know how a black hole is formed? It is formed when a star dies. I think sometimes, that's the best metaphor to describe a drastic change that you feel in you.
A star exudes light and it is the reason for the existence of life. When it dies, it is replaced by a dark black hole that is the embodiment of darkness and death. Nothing escapes it.
There are times in life when you feel like a black hole. You feel as though you have this deep void within yourself that just can't be filled no matter what it consumes.
Your thoughts inevitably travel back to the past when you were like the star, filled with light which symbolizes happiness and joy. You can't help but miss that old version of you.
Then your mind wanders to what led you to feel like a black hole. You can't help but wonder if it will always be this way if that old version of yourself will ever return. It's easy to get lost in the sea of disappointment and hopelessness.
I don't have an answer to what you should do if you ever feel this way. If I did, I would probably use the same advice on myself. I only know that you have to exist, no matter the odds.
It is said that the universe can make miracles happen. And although it might seem like bullshit sometimes, who knows, a miracle might happen and you might be saved. Maybe the void inside you will be filled one day and you will finally feel alive again.
