Need advice please?

Hello, I'm a mother of an 8 month old going on 9 months. I'm exclusively breastfeeding. I'm 22 going on 23 in September, l'm a SAHM who dropped out of college after half as semester because I experienced seeing a pig get gutter at Texas tech (I was in the veterinary program) I'm stressed, my fiancé doesn't mind me staying home until baby is bigger but mentally I don't know if I can, but the problem is paying for daycare and I really wanna go back to school but at a community college to start off small. We don't have enough fund to pay for me to go back yet, online jobs are hard to obtain in my opinion. I would ask my (village) family for help but they live more than an hour away. I'm gaining weight by the pound I'm 162 pounds now, my pre pregnancy weight was 145. I just need advice, how should I be navigating life, what should I do first?, should I just suck it up and stay home? Will day care be a waste of time?
