If you get fired from your job then there is no need to be emotional. Tackle the whole situation with a big heart and do not panic at any cost. If you believe in God then remember that he will take care of you and you need to be patient. Who knows, it may just be a test of your faith and God has something much better installed for you in future. So never lose hope in such a scenario.
There is no need to argue with your employer and keeping cool is the key. Other than that, you must not show a poor body language in front of your family or friends, as it will depress them as well.
Assess your financial situation
Now that you have been fired and you do not see a salary coming in near future, you need to assess your finances and spend money very carefully. Make yourself understand that you cannot afford any luxuries in this scenario.
Take some deep breaths and think about your career for a while. Get yourself mentally and physically refreshed before you start the job hunt. Send your resumes to different companies. It is your right to find a job according to your academic background, experience and merit; however, until you find reasonable employment, you must not hesitate to accept any offer. You can even work in a restaurant or do any kind of a work, just to ensure that you are not depending on someone else.
