["I lost my mind and temper, when i have been told i won't be promoted", "That must've really upset you. Did they explain why?", "yeah it did, it was deserved one but they didn't explain and i am so angry right now!!"]
Definitely take some time to vent out your anger. It's totally undestandable.
I lost my mind and lost temper when i came to know that i will not get my deserved promotion
