As in life we're often surprised and fear the way events unfold. Something we initially might think as being a negative or a positive experience can often lead to a positive or negative outcome, because we've found another door that's opened to us when one has closed, one that we'd never imagined.
It doesn't mean that this all will unfold in an easy manner, and it might be the case that the very opposite will be our reality. We may feel we've gone from the frying pan to the fire and have been completely kicked to the curb, but regardless, the end result will eventually be transformed into something better than what was before or maybe not. We do however have to find a way through.
