Sorry for the long post just need to vent.

Finally went back to work tonight. It was supposed to be a short not even 5hr waitressing shift at a family friend's restaurant. Left my son with my older sister& he literally screamed for an hour straight to the point she had to bring him up there& I had to leave early. I was (and still) feel mortified. I'm supposed to work again Sunday night, just not sure if I want to now though. I just feel so defeated and I feel like an ass because my sister had to put up with him.
