My mother is a child

[u/datdude985]

So let me start by saying I love my mother more than my self and that maybe part of the problem.

To start from the beginning my father abandoned my family when I was 17, I am one of 5 children and second to oldest. So my mother having no work experience needed help so we lived in a tiny apartment (oldest child my sister excluded she past away) and I helped paid the bills at 17. Now fast forward a few years things got better she worked alot and seemed to be able to handle most of the bills on her own so I moved out but still sending her money when ever need be.

Fast forward to current day I'm 26 and still helping with the bills but now it seems alot more and I couldn't figure out why. Come to find out she was fired for being late and didn't even tell me had to find out from my brother.

I do not know what to do bc she still has 2 of my siblings 10th grade and 7th grade living with her and if I try and cut her off this will put them without food or electricity. She seems to have no work ethic anymore and gets super defensive if I bring it up. I'm doing everything I can but I make about 75k a year witch is very good for the area we live in but not enough for my house hold(me my fiance and my brother who lives with us when he is not in college and I still send money to him when he needs also) I just don't know what to do I'm always giving them my last dollars and have gone eating only penut butter sandwichs for a few weeks.

What can I do to help this woman grow up and just finish taking care of these last 2 kids, all I need is a break I don't mind helping and I definitely don't want my siblings to have the childhood I had with no food or running water every few months wtf can I do.
