Fear of going to office. Such things.

I m facing some problems with re-joining office. Actually I quit last org bcos my immediate boss doesn't like my work as well as me. She once said I do donkey work n more Dan many times she insulted me in private and public both. I cried many times in office n other my collgues also told her but she didn't understand. She took help of some other friend of her n throw me out of org. I m home from July n now I m facing fear of going to office again I tried giving 1 interview but I failed miserably n interviewer insulted me .i m facing fear now to go to office even if I by chance get selected in some org. I fear that I may make mistakes n people will again laugh at me or say me wrong things which happened often everywhere say home office or friends. They all just say I m not doing enough or putting efforts which is wrong. I failed in everything in my life. So my parents are also not happy about me neither my boyfriend. I m tired of failures n now fear more about  such things.
