I don't think you need more details, its personal to you. leaving things out makes us want to read on.. and see whats happening. your poetry doesn't need to be grammatically correct - it needs to portray what you are feeling. This is excellent, and could be applied to so many different situations - physically, emotionally.. or what have you. You are a great writer darling :)
This poem has a very strong, powerful voice. It has so much potential. I really like the line "pain eats" and "blood contaminated". I think "this is more than me" could be worded "this is much more than me". also, the readers are left with not knowing much of what is going on. put more details...encorporate all of the senses, sight, hearing, smell, touch, et cetera, so the readers can experience the feeling of the poem in the same way you did, and so they know what's going on and can more fully understand what the poem is about.
Also I'm not sure if "watching away" is grammatically correct, it might be but it just feels off place to me, but it's your poem so feel free to leave it there if you like it.
