I have 0 savings and risky job.. should i stay in expensive city or move back home?

I am living alone and have a job that pays the bills and all that in the expensive city i moved to a year ago, and i like it here but this job is stressful and also very unstable currently and i am afraid of being fired, even though ive worked there for about 2 years now.. very toxic workplace and people are being fired constantly.. i have made myself as valuable to the business as possible but it still gives me anxiety… the worst thing is i dont have savings or a backup plan.. i dont want to move back to my home country because i hate it there… ive been trying to get a better job here but its so difficult to find one. In my home country it wild be much easier but there are no high paying jobs at all, and again, i would not be happy living in that environment.

I need an outside perspective of how risky it is to stay here… what do ppl usually do when they stop having a monthly income?? What would my options be (NO moving back with family).. my biggest fear is moving back with family or being homeless.

Just for clarity, my home country is a small one in Europe that is safe so no wars and stuff to be concerned about.. however the ppl are stuck up and no opportunities whatsoever.
