In what country do you reside?
If you live in the UK, or most western European countries, you could probably, at the very least, get some sort of "carer" allowance if you have to financially support your mother.
The US situation is a little more difficult. Especially with COVID. Though Amazon is always hiring.
Let me emphasize that I'm not "judging" or anything like that. Especially since I don't know the complexity of your situation.
