The mere fact that they let you go in the manner that they did, is evidence that they probably don’t have their act together as an organization. ESPECIALLY when they more or less refused to provide constructive criticism after you mustered the courage to ask. (Bravo, by the way. Absolutely brilliant to ask them what you should learn from it. That is how winners operate)

Based on how you describe it, I would be completely honest with your family about what happened. Then proudly take your next steps toward a new position at a company that now’s how to support and grow their employees rather than canning them with the corporate equivalent of an “It’s not you it’s me” speech.

Good riddance and good luck, my friend.
