I really like this. Good strong, simple melody.

The only suggestion I can make is about the lyrics. If it were me I wouldn't change the subject (in grammatical terms!) between the verses and the choruses. Presently, the verses refer to first person ('my') while the choruses refer to 3rd person ('you'). Personally I'd make it 3rd person ('you') all the way through so the audience would identify with the whole song. Hope that makes sense?

But great job overall.
