"You are what I would seek on a gloomy day,
And would love on a rainy day,
But can't do without, even if it's for one single day."

I recommend not rhyming a word with itself 3 times in a row, it disrupts the flow and feels like unintentional repetition. Otherwise the substance presented within the poem was mildly thought provoking, i feel that a wide audience can appreciate and sympathize with the feelings therein.
