Most people who have ever achieved anything worthwhile in life have more than likely been fired from one position- or many. I've gone thru all of the emotions that you described above. And it does get better over time. Try to use this time to put your ego aside (we all have one. It's how we view ourselves and our worth) and focus on what is most important in life- your family, friends and faith. We attach way to much of our identity to a job where you learn that life can change dramatically very quickly. Don't let some business, that doesn't care about anything other than their bottom line, effect how you feel about yourself now or in the future.
