Local simp's Things

I'm not expecting any glamorous jobs to hire me. I heard that a local fast food place was hiring so I wanna try landing a job there.

Resume:
I am 21 years old and graduated highschool but have no prior job experience (babysitting, mowing lawns, etc. I'm useless I'm sorry ). What do I even put on my resume? I read that I could put down what I did for extracurriculars but I only ever did orchestra in middle school but stopped in hs. Other than that, I didn't do anything but like art lmao. I'm also not going to college or uni because I'm broke, my family's broke, and I don't wanna risk going into debt.

The interview:
So I managed to land one interview before but got rejected because I was so nervous and was just coming up with answers on the spot. Does anybody know what kind of questions they ask so I can like preplan answers instead of letting my dumb ass brain mess things up? Also, what's the appropriate level of eye contact I should maintain throughout the entire interview because I think I stared too much at the interviewer in my last one. Another thing, I don't have a driver's license but I have an expired passport than I can possibly use as an ID, would that be acceptable? (Please don't be afraid to tell me if I'm fucked if it's not)

Taxes:
What do I even do here? Do I like jot down how much I get paid every month and then set aside money to give to the IRS? I don't want to get arrested for accidental tax evasion.

That's all my questions for now. Job havers, please save me from being a broke useless jobless bum.

Take this with a grain of salt
Once again, don't talk about mgg outside of mgg people

I just got logged out multiple times and some things aren't loading for me like manga covers, comments or my profile. I almost freaked out when my profile or notifs wouldn't load, I thought my account got deleted or sum

I'm trying to find a job but was rejected from fast food places, y'know the usual. I'm over 18 (not saying what age for privacy reasons), I do not go to college or university or trade school or anything really, I do not have any previous job experiences. I'm not good at socializing or dealing with people (likely why I got rejected from retail or fast food). I'm not good physically (meaning I'm not strong, I think I may be suffering from an iron deficiency too) and I think I suffer from undiagnosed anxiety. I don't wanna be useless anymore. Frankly, I would've just either killed myself or continued leeching off my dad but he's divorced, supporting 2 kids (excluding me), and has a gf and baby abroad he's supporting financially (i have no idea why but he's an adult so idc). The guilt's been eating me up, I feel like a huge piece of shit tbh not doing anything and funerals are expensive so I want to get a job.
So people of mangago who are/have been useless shut ins like me, what kind of jobs can I do? Probably not a lot but honestly I'll take anything at this point.

Tldr;
I need a job, I've been rejected by retail and fast food
I have no prior job experience, I'm over 18
I'm not good at socializing but I can try, I'm not good physically (and mentally really)
Please tell what kind of job I can do in my situation

Srsly! I literally just logged on like 5 min ago and click on a new chapter and was sent to a porn site! So annoying! Fffff
