Is this sonnet ok for school?

The only thing I see wrong with it is that you have a little confusion at the end. I can tell this is about someone chasing you and catching you but there is this last verse that is not quite right. I think you need to change it to something more to show how the attack-if this is what it is-ends a little better. Do you mean that his life is lost and you find that you can't forget how he died? You see, people can come up with a lot of different ways of reading this. If you're not careful by the way you write things you give a misconception of what you intended. Be careful of how you write your poem.
