You want me to do what?

So I applied for this job about a month ago and I got it. Today was my first day, and I already want to quit. See here's the thing; the job I applied for was an office type job, cleaning things up, and organizing and the like. I found out today that I'll be working with kids and trying to convince more people to join. I'll basically be doing what my mom does.

This is stuff I cannot do. Mentally and physically it's difficult to the point of impossible. I don't like dealing with kids (no matter how much they like me) and talking to strangers, much less convincing them to do something, sends me into anxiety overdrive. And I'm already to anxious for my own good.

The lady who runs the place is super disorganized and thinks that vague instructions are enough. So when I ask questions she looks at me like she's pissed that I can't read her mind.

I just don't think I can work in that place, it's not for me. At the same time though, I really need a job. Ugh, I wish I just knew what to do.
