I don't know what to do

My cat is important in my life, I'm panicking since she's straining to pee ever since afternoon, (She May have some bladder blockage or UTI, idk) I know there's a problem with her and she needs to immediately taken to a vet but the thing is, things are rough nowadays. I don't have a job, my mom just lost her job last month and I'm still studying. I'm just in college, struggling with tuition, my family doesn't have money either, I'm living day by day eating noodles or processed food, yes, I can't afford to take her to a vet considering the vet is very expensive, and I live in Philippines. I can't take a damn loan, but I can't just let my cat suffer, I don't want to lose her like I've lost my cat before.
