URGENT NEED HELP

my dads disabled

my mom was notified she was getting a job within this week, but there have been no calls since, and she has no job. she called them back, and they said theyd hired someone else who was somehow related to them.

my mom asked me to quit from my job and i gave my two weeks notice, which is up on thursday. this is becuase once she started her job id no longer have a ride to get to work since it is far.

but i cant quit anymore, becuase otherwise my family will be left without anyone to fend for us.

i dont want to look like a fool and begfor my job again, but i cant quit now. what should i do and say to get my job back...

will i still be able to keep my job?
