Okay, I made a few changes within your poem. I pretty much separated the lines where it needed so that it could make more sense.

Also I changed broke to broken in lines 4 and 5.
As well as added Now in front of I know the truth in lines 13.
I added Within at the end of line 14.
and at line 15 I changed your to you are..
and a few other changes that I forgot to mention right here.

Such loneliness you have given me
I'm taking my time in healing
but the wound will not close
you have broken all my souls rights to exist,
broken the path I have walked.

The pain I have can never be erase
no matter how long I lie here.

This is not helping
all the life I had ever held
has been striped away
from the joyful soul I once had.

Such hate you have allowed me to own
I must say thanks for I
now know the truth of your breed
I now know what kind of soul you have within
You are a demon sent to me from the devil himself
to ruin the feelings I have ever had.
