Dear brother

I think that youre not failed, but temporarily facing mental block. you can read about the concept online.

in our age, i dont think anyone can be judged as failure or success. the successful are those who are remembered positively long after they have left us for the next world. we should try to be good humans above all.

remember not all times our plans work for us, Allah (SWT) has better plans for us. I wish you best of luck and success and I request you to use the meantime to give a few KPSC/other commission tests for various jobs - just giving the test will overcome your fear. Use your time to learn more, read, do free online courses, develop yourself as a good human, use youtube.

Long journey is ahead - not to despair, I leave you with this image only.
