A few weeks ago a lady at my job got a promotion i thought i was going to get.
Oh no! I am so sorry. That is really tough.  
It was really a tough one to swallow.
Did you get any feedback on what you could do to improve your chances next time?
Nope. I think it was just favoritism to be honest. 
Ah, that happens.  Again, very sorry. Maybe you can find the silver lining in it. Or, find a new job and get a fresh start somewhere else.
