My honest opinion: There's a lot of space for improvement here. Most important one is the lack of punctuation.
The rest is below:
The first 3 stanzas are exactly the same, just phrased differently. I'm all for repetition but it should have a purpose, which I can't find here. Speaker is lost in the darkness, looking for light.
There's this saying in writing called "Show not tell". I think the poem needs more of that. How can you show that the speaker is lost in the darkness, wandering, looking for light? Why is the speaker lost? What does he feel? Remorse? loneliness? Will the speaker ever escape? If not, why? Does the speaker have a weakness or barrier that prevents him? Or perhaps the speaker doesn't want to escape? If yes, why?
Maybe write it in a way that answers some of these questions without actually saying it. Or else it will only be:
The speaker is stuck in the dark, wandering, losing his mind. But there's nothing else after that. This can make the poem hollow.
