What do I do in this scenario?

My girlfriend used to work at a walgreens in a small town. Well we move to a city in our state and this place is understaffed and she's a supervisor doing multiple jobs at once. She gets over whelmed and ends up being put on a leave for her mental health. She gets a grooming job not too long after and once again gets a bit overwhelmed and the pay was not helping. She recently got a call center job. They did not train her really at all and the help she has sometimes doesn't answer for hours. They put her in a more active que yesterday and she just walked out. Of course she lost her job after that. I love this girl but she keeps putting us in tight spots. I work full time but don't make enough to keep us both afloat. We were just now starting to catch up but now I don't know what we are going to do. Each time she started something new it set us behind. I love her and trying to be there for her. She's not doing good with any of this at all. I'm just lost on what to do.
