This will be easiest for me if I take i stanza-by-stanza. Please don't think I'm trying to be mean or rude.
"I envy the flowers that bloom in the Spring
Thriving with rebirth while I wither each year
A new season, a new life, melting into beauty
I-without identity or purpose linger aimlessly"
This is the most powerful stanza. It reads beautifully and has the most punch. I would only mention that, in the last line, "I-without..." should read "I--without identity or purpose--linger..." Grammar. It's a killer.
"I watch the water drench the ground
It fills me with a guarded hope
To one day be filled with aroma and life
The sun infiltrating my every need"
Is infiltrating the right word? It sounds off. There are several factors I'd play with here. The whole flower analogy could be better articulated. The "guarded hope" could be expounded. All in all, I'd take a second look at this stanza.
"A cycle in which I accept and embrace death
For I will rise again in the year to come
A new beginning, a new life always ahead of me
I, always wanted and loved by all"
I think that you should add the word "must" in that first line. "...in which I must accept..." I think that would better support the metamorphosis that the poem embodies. The last line shouldn't have a comma. It throws the reader a tad.
"To birth in the Spring and die in the Fall"
Whatever traction you lost from the first stanza, you make it up with this last line. Incredible ending.
Just my two-cents, take them or leave them,
