How to add punctuation marks? A poem I wrote myself. Missing is like a seed buried deep in my heart.

Missing (the title of the poem is not used elsewhere, there is no title)

Missing is like a seed,

Deep in my heart, deep-rooted

Missing is like a budding seed,

Better every day.

Missing is like taking a boat in the sea.

In my heart, shake, shake.

Either each sentence has the same number of words, or it is an ancient poem. Don't try to punctuate, every sentence is the same length.
