I’m messing up almost everyday at work

I’m just not sure I can keep up making minimum wage, paying my bills at this rate. It’s been 5months since I joined the company, but there’s always something that happens everyday/I mess up which makes me slower the rest at work. Through all the shit I mess up for others, some of them are more than patient with me and are stern not mean which makes me feel horrible. My supervisor has gone above and beyond to check on me and help me slowly get the hang of the job.

I just want to be able to keep bare expectations and even that seems hardly possible sometimes. Am I just that incapable?

my parents have taken care of my expenses my whole life, I just want to show them I can handle a job in a different state, pay my bills and help them financially eventually.

logically speaking, I know worrying won’t help in anyway but it keeps me awake at night regardless.
