Am I doing too much for my mom

I don’t know where else to turn to since this is my only source of social media.. my mom is at risk for being evicted from her apartment if she doesn’t come up with rent money by the end of the month. (She’s two months behind). Of course we are all very stressed out because she has been homeless once before with nowhere to go. I’ve brought her to my home on two separate accounts until she got back on her feet with (car, house and job) and this last time was a success, until someone T-boned her and totaled her vehicle. Since she was a caregiver, she couldn’t return to work without a vehicle or insurance. She somehow doesn’t qualify for state unemployment(may be due to her moving to this state and only working for a little under a year..not sure) I live 30 minutes away from her so it was a challenge even looking for jobs trying to take her back and forth. So being her daughter, naturally I wanted to help. So I’ve paid 4 months of rent without my husband knowing Including groceries and utilities. Even my hands have been tied this entire time with two jobs, nursing school, I’m now 36 weeks pregnant with my first child so I’m on maternity leave w/o pay. I applied for programs to help her but we haven’t heard back from them yet. Our family is located in a different state so I’m the only one she can depend on to help her.. I helped start a gofundme for her yesterday in hopes that many would see it because it’s our last resort. So far no one has viewed it or helped. It’s definitely a strain on me and my husband to keep “figuring out” what’s next for my mom to help with basic needs. It definitely stirs up disagreements between us… since the responsibility and added stress has been on me. My husband thinks that I am doing way too much for her and wearing myself thin… Tomorrow I have to drive 30 minutes to pick her up, drive an hour and a half away for the second day in a row and pray that the Salvation Army helps.
