As Patrick already told you, unfortunately, there is nothing you can do at this point.
The only thing I can suggest is asking your agent to try and find out why it was withdrawn, and to make sure the other agent notifies her if it is coming back on the market. Maybe you'll find out that the withdrawl is only temporary......but in any event, you will want to make sure you get a heads up if it's coming back.
In the meantime, I hope you find a home you love more!
