How do I get a better job?

I just started this job five months ago. Thought I would be able to stick it out since I wasn’t finding anything else.. but it’s not good. 30k a year after tax, no benefits or PTO. My car died - so I’ve been using a friends extra - but I can’t much longer since she’s moving come the new year. I haven’t been able to save much since this just doesn’t give me enough to buy food, gas, rent, etc...

How do I move? Been trying for a second job but I’m not sure if I’ll get it(interviewed yesterday)

I have a BA in HR. Current job is admin assistant at a non profit.
