'From bad to worst'

It starts off good
And often stays so
And from time to time
Ones will return to it
Never wanting to bend
Like an addiction ever flowing
As dreams revolve at times around it.
Indeed-
Until it hurts you!
Until that which brought you pleasure,
Becomes a burden
Sad or mad?
Yet if you can live with that-
You might be able to rise above anything else she throws.
