I need to know if this Sonnet makes sense?

I wouldn't worry; it is understandable and well-written, and you maintain pentameter the entire way through. The only critique I'd give is that you don't always follow iambic rhyme, but that's difficult for professionals, never mind for a high school student. Also (and I apologize if this is nit-picky) but in the last line, the phrase 'worst present of all' really bothers me. I don't know what you'd change it to, but at least in my mind, it throws a wrench in a poem that was going along quite nicely. Then again, this is probably better than anything I could write. Good job; I enjoyed it.
