Come on, stop torturing yourself any longer. Listen now. Go home and don’t come out for a couple of days. Don’t pick up the phone, don’t get online, and don’t check your e-mail. Avoid TV and radio. It is important to not get distracted. It would be best if you simply lie on the bed and stare at the emptiness. Take your time to think about what happened, understand it and accept it. In a few days you will feel better.
You will see.
