should i stay or should i go now?

i had a really shit day at work. too too many mistakes. i wouldn't blame them for firing me, but god i can't afford to lose my job. and i don't know how to stop making these same mistakes. i wish i was perfect, but i'm not.

is quitting the appropriate thing to do? should i? i don't want to, but it seems like i just can't do my job how i should. maybe this really just isn't for me.

i just don't know.
