Excellent poem and nice flow.
deep emotions mixed with pain but make sure of one thing. if you died then it's over but if you lived and kept looking you will find happines one day FOR SURE...

This was great:
Now I lay me down to sleep
I pray the lord my soul to keep
While angels watch me through the night
And demons hide from morning light
^^^
It made me smile - nice flow

Though I was confused with one thing. Your first stanza shows hope because of the "protection" and that the person is praying but then the subject kind of jumps to the character dying ... (I'm honestly just confused and would love a explanation from you? For a reader :D)
