Hi there, mordax!

This poem has some nice literary symmetry, and an interesting theme. It may be morbid, but somehow soothing to think of the speaker as having a positive or rather accepting view of their death, especially in "there comes a time to resign".

Free me from Its snare

First I would like to ask if the meaning of ‘Lime’ in your poem is - according to the dictionary - treat (soil or water) with lime to reduce acidity and improve fertility or oxygen levels.
If so, I must say that it was a clever idea to write a ‘fertile’ gravestone (paralleling death).
My second point is that I like how Death is not seen as the villain, but as freedom, it gives another perspective into what it is to live.
Is life always good? Or is there pain to it? In my opinion, this poem addresses this with the ‘I hope that it will someday read/ of a life without a crime’. It highlights that even people who did everything correctly will still suffer and die, but the latter shouldn’t be seen as vile.

Hey there!

Somewhere lies a gravestone just for me
It’s unmarked and carved from lime
I hope that it will someday read
of a life without crime
I near the end of shortened Time
but fret and worry not
for there comes a time to resign
And pain can be forgot

I beg, do not fight for me
It’s so much more to bear
Life is chains, you have the key
Free me from Its snare
I will fall in Death’s gentle care
and somewhere there will be
Unmarked and carved from lime
a gravestone just for me

A powerful and well written poem from someone about to die-an unusual and interesting topic for a budding youth just blooming into the full vigor and energy of adulthood. A worthy challenge!
Typically, a person's last words contain something that sums up their life, or the moment of their death. A final statement may also include personal messages to loved ones, bearing in mind it may be the last time you speak to them, and your desire to impart one last bit of live advice to be remembered by, before you leave this. Also, you could include some assurance that you will always be watching over them, and will see them again one day. These are the kinds of typical and/or personalized details I feel could make your poem more realistic, as well as emotionally resonant.
What you have is technically well written and interesting, I just feel that with a bit more consideration, and a few more stanza's, you could do something so much better. Potential is there.
