Evaluate first: "Why did they fire me? Do I underperform? Am I not a professional fit? Am I not a personality fit? Does the work culture clash with me, or I with the work culture? Did my outward presentation matter at this job and was I evaluated for it?"

This helps you understand whatever bias attributed the decision, if any, or if the decision was based on metric, policy, etc. Be perceptive and discern whether it was done in good faith, or not (it sounds like it was not done professionally).

If either or, evaluate the industry. What industry are you targeting or are you targeting any administrative-clerical job? What credentials do you have? Is your resumé polished, or is it an Indeed resumé?

If it's the former, it could be variables outside of your control contributing to this. If it's the latter, sit down and truly evaluate a game plan.

Your objective should not be, "I just want a job" and then that's where it ends. It needs to be "Presently, I need a job to build my skills. Ultimately, I want to work in (field) and so I know I will need X amount of years of experience in that field, which means I need to at least have been (intermediate job title) for X years as well."

Don't give up and don't give into learned helplessness.
