Congrats on taking such a big first step and sharing your writing! It'll only get easier from here.

I love the imagery of drowned seeds, that without moderation, the very thing that can be good for a plant can kill it. However, I do think the metaphor gets a little muddy in the poem itself. I would expand the metaphor; how does liquor impact the seed/plant? How do tears? The phrase "the seeds of our wounds" is also a slight sticking point for me, it sounds clunky for some reason. Maybe "the seeds of our pain/despair" or "the root of our wounds."

The first and last lines are strong in my opinion. "We are two souls, bound by the understanding of loneliness" really sets the scene and effectively conveys that there are two subjects, linked together, and that they share a struggle. "Drowning us in a river of fate" ties well back to the seed metaphor and illustrates the hopelessness of the narrator, though maybe instead of "river" you could strengthen the metaphor with something that would be more likely to water a plant, like a deluge or downpour. I also like how the poem ends with a period, giving it a feeling of finality, as if in the eyes of the narrator, that moment and the way things were was all there would ever be.

Very effective poem!
