If your interpretation of the metaphor is correct, it's an even worse metaphor than originally thought. "Your life can be compared to a chocolate candy bar. You can never get rid of the candy bar, you will always have it and you absolutely must partake of the candy bar whether you like chocolate or not, your only option is that you can bite from the other end of the candybar. Because metaphor."

Sadly, we have to work with the metaphors we're given. In the case of the fictional house with many floors, I can most definitely move from it to escape a shitty foundation. You, it seems, can not. I can't help you with your house, I can only worry about mine. Best of luck on your house.
