In America's Society it is extremely common for people to be defined by the jobs they have.When getting to know someone, inquiring what they do for a living is first priority. So after you lose a job, it is not eccentric to feel embarrassed, worthless, or a decline in your over all self confidence.
It is okay! Almost everyone goes through those emotions. You don't want to stay in this place of emotional anguish to long. You need to be in the right state of mind mentally if you plan on getting back to work soon.
A job is just a place where you put yours skills to work. Whether you have a job or not, you skills still belongs to you. Your job does not define you. Your abilities define you. Every individual has a purpose in life. If you were laid off, then quickly realize that job was not your purpose. Work on getting to that place in life your you are completely happy with yourself. Hope this helps and God Bless.
