Hold your head high man. Nobody consider a someone successful for what he has achieved but for the journey he has been, from where he has come. That was humiliating, no doubt. I know you feel like killing yourself. I have been there. But trust me, he didn't do to humiliate you. Maybe he was helping you or just himself. It wasn't personal. Sleep. Give it 2-3 days. You will stand again to face the world. In the huge cosmos of your life, this moment was a tiny ripple. You're bigger than this. These moment don't define you or your life but stepping stones of your great life which is destined.
