LeeAnne,
I am a firm believer in fate and that everything happens for a reason. The real reason as to why you did not get this job will show itself somewhere down the line and you will be amazed that the reason, 9 out of 10 times, is in your favor. Believe this to be true. It has happened to me more times than I can count.
My mantra in life is "This too shall pass." Hold onto this and look ahead to something better down life's road for you. In the meantime, allow yourself to be angry and disappointed - for a little while - and then more forward to something that gives you happiness.
You are a winner and there is something more worthy of you and your talents just waiting around the bend!
