Loser

I was thinking that if people like me who are just average and very often below average at performing tasks, if we were never born it wouldn't have made even a tiny difference in the world?

I'm particularly asking for what worst could have happened if I was never born, except for my mom and dad, like every one in my life all my friends/seniors/colleagues would have found a better alternative of me, why does it matter if I exist or not? It wouldn't matter to anyone except for my mom and dad if I meet a fatal accident tommorow? I have worked hard for so many years, I studied 5 years of law school, did multiple internships across multiple cities, took courses, attended seminars, just to know at the end of the day that 76-80% of the work I do is just average and doesn't make any difference to the institution/senior I work for, I was a below average kid in academics despite studying day and night, I messed up my sleep schedule for life, coz of the constant examinations I gave throughout my academic career, I landed up in a decent office/chamber in a tier 1 city but then after an year of working I realise, that I am just there as a kind of formality, that the work I do is so average, full of errors and lack depth that 70-80% of my work doesn't actually make any difference, that people who joined the field at the same time as me are performing way better than me and have achieved a way lot than me and the funny part is this is the career I chose for myself, this is something I am and I have always been passionate about and now I get to know that I suck in this too, I thought I am bad at academics but I'll perform better at work but hey I suck at work too even after 1 year of *** slogging hard work and dedication, negligible leaves and forced attention for hours upto a point that I have lost my sanity to 24 hrs anxiety but all that for nothing, maybe I'll just remain average/below average despite my 100% efforts, at this point I just wish that all this ends for good
