The Sick Rose

I feel like this poem is kind of confusing. I don't really like it because it's kind of hard to understand. I think something could have been added for more clearification. Personally, I may be wrong, to me this poem is about jealousy. I think it's about how people will try to ruin your joy, your happiness, success, wealth, and any personally growth that for the better yourself. I think it's about how jealousy can really kill a person because they are always focusing on others and not themselves and getting their own personal growth.
