Procrastination

does anyone else feel like they hate hanging out with friends 75% of the time?

they all think i hate when they cancel our plans but i honestly don’t, i love just staying inside and treating myself.

like i don’t hate them it’s just that i love myself more

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
