You're fired. Take a deep breath. This doesn't define you. You will find a new job. I think you are a good engineer who put many years into a company! Be proud of that. You're also a person who stood up for yourself! Be proud of that as well. Most people wouldn't stand up for themselves. Take a walk, if you can. Maybe 4km. Don't think about work, career, or anything. Just see whatever you can see. After you get back…
Thank you, I am doing it today.
You got this!
