I believe i understand the fellings in this WELL WRITTEN poem

the only suggestions I have is correct the spelling of support and add the word have in the second line

Grunt and sweat under a weary life
often with myself I have strife.

thousands of cries all full of rage
trying to free this bird from it's cage.

if only these wings moved,
this bird would be removed.

Why me?

what good are feet when one can't walk-
what good does a mouth do when one can't talk
what good is a soul if one is still as a rock.

This chair meant to provide me support,
has become a cage, but was a last resort.

I want to die, be set free
be taken off this wheel chair, out the cage

5>>>>>>
and use my wings to flee

I am disabled, at such a young age
I am a bird, locked up in a cage.
