Is this a job that works with the jobs you need to take? ( I believe you need volunteer positions or positions under a certain amount of money?)
It would help to know if "job B" was available to you with transportation/bus passes, etc.
I admire you for trying to keep busy and working, however, sometimes the added stress and logistics of transportation, etc., aren't' worth it.
You said... I added punctuation and corrected spelling, to make it easier to read:
"Thanks everyone .
I talked to my mom earlier, big surprise right?
She did not have a kind word for job b nor did she think I had the time, since jobs As hours are unpredictable.
Is there a way to let job b know I am no longer available?
when I applied, my hrs were very different then boss of job A.
she needed more"
